PE is insoluble in any solvent at room temperature, but soluble in aliphatic hydrocarbons, aromatic hydrocarbons and halogenated hydrocarbons at higher temperatures. For example, LDPE can be soluble in 60 benzene, HDPE can be soluble in 80 90 more than benzene, more than 100 both can be soluble in toluene, trichloroethylene, tetrahydronaphthalene, decahydronaphthalene, petroleum ether, mineral oil and paraffin.

Polyethylene has excellent chemical properties and is insoluble in all currently known organic solvents.

Polyethylene (PE) is a thermoplastic resin prepared by polymerization of ethylene. In industry, it also includes copolymers of ethylene with a small amount of -olefins. Polyethylene is odorless, non-toxic, feels like wax, has excellent low temperature resistance (the lowest use temperature can reach -100 -70 °C), good chemical stability, and can resist the erosion of most acids and bases (not resistant to acids with oxidizing properties).

It is insoluble in general solvents at room temperature, has low water absorption and excellent electrical insulation.

Hope it can help you, thank you.

Hello, I am glad to answer for you, polystyrene can be dissolved with xylene, acetone, methylene chloride and other solvents. Polystyrene (PS) refers to a polymer synthesized from styrene monomer through free radical polyaddition. It is a colorless and transparent thermoplastic with a glass transition temperature of more than 100 °C, so it is often used to make a variety of disposable containers that need to withstand the temperature of boiling water, as well as disposable foam lunch boxes, etc.

Summary. Polypropylene can be soluble in toluene, decahydronaphthalene, DBP and DOP, etc.

The production process of polypropylene has mainly gone through several stages of development: solvent method, solution method, liquid phase bulk method (including liquid phase and gas phase combination) and gas phase method.

What solvents can polypropylene be dissolved in.

Polypropylene can be soluble in toluene, decahydronaphthalene, DBP and DOP, etc. The production process of polypropylene has mainly gone through several stages of development: solvent method, solution method, liquid phase bulk method (including liquid phase and gas phase combination) and gas phase method.

Toluene is generally used the most.

How polypropylene can be soluble in methyl grease.

Solution polymerization, emulsion polymerization and copolymerization are possible. Solution polymerization usually takes place intermittently, a monomer or mixture of monomers is added to a solvent, heated and maintained to an appropriate temperature in the presence of soluble peroxides and azo compound initiators, and the polymerization reaction proceeds smoothly until the reaction is complete.

Polypropylene, methylformamide, dimethylformamide heated at 55 degrees, how can polypropylene still not dissolve.

A certain amount of catalyst should be added.

The catalyst is that material.

The catalyst is that material.

One is the water and the other is the stirring time, try to use the granules with a larger dissolved area, the temperature is about 50 degrees, and it can be stirred properly.

Polyethylene is a linear polymer that can be partially soluble in some organic solvents. It can be dissolved with organic solvents such as benzene, toluene, etc. The information is as follows: Polyethylene is a white waxy translucent material, flexible and tough, lighter than water, non-toxic, and has superior dielectric properties. It is flammable and continues to burn after leaving the fire.

The water permeability is low, and the permeability to organic steam is larger. The transparency of polyethylene decreases with the increase of crystallinity, and the transparency increases with the increase of molecular weight at a certain degree of crystallinity. High-density polyethylene has a melting point range of 132-135oC, while low-density polyethylene has a lower melting point (112oC) and a wide range.

It is insoluble in any known solvent at room temperature, and a small amount of more than 70oC can be dissolved in toluene, amyl acetate, trichloroethylene and other solvents.

Hello dear, according to the situation you described, polyethylene is a polymer that is not easy to dissolve at room temperature. However, there are several ways to try to dissolve polyethylene: using chemical solvents:

For example, chemical solvents such as acetone, methylene chloride, chloroform, etc., can dissolve polyethylene. However, it should be noted that most of these chemical solvents are toxic and volatile, and it is necessary to pay attention to safety when using them. Thermal dissolution method:

Heating polyethylene to its melting point (around 110°C) makes it soluble. However, this method requires high-temperature treatment of polyethylene, which can lead to degradation and other quality issues. Mechanical Strengthening:

Through mechanical forces, such as high pressure and agitation, polyethylene can be broken down into smaller particles, which can then be dissolved in other substances. It should be noted that polyethylene is a common plastic material, and environmental protection and safety issues should be paid attention to when handling and disposing of garbage.

Polyvinyl alcohol can be dissolved by heating it in water at 90-95 degrees. Polyvinyl alcohol is used as an emulsion stabilizer for the polymerization of polyvinyl acetate emulsions. It is used in the manufacture of water-soluble adhesives.

It is used as a modifier for starch adhesives. It can also be used to prepare photosensitive adhesives and sealants resistant to benzene solvents. It is also used as a release agent, dispersant, etc.

Polyvinyl alcohol 17 92 is abbreviated as PVA 17 92 and comes in white granules or powder. Soluble in water, dissolved at a temperature of 75 80. Other performance is basically the same as that of PVA17 88.

It is used as an emulsion stabilizer for emulsion polymerization. It is used in the manufacture of water-soluble adhesives. Store in a cool, dry warehouse, fireproof and moisture-proof.

"Wet" the solid seal of polyvinyl alcohol with alcohol for about half an hour, open it, add boiling water or distilled water, stir until viscous, move the container to the water bath (or oil bath) to steam, and then simply put the pressure cooker or rice cooker at home... It's about the same for half an hour of steaming over water, and it doesn't matter if you don't stir halfway. It is faster than dissolving directly with water, and it is best to add some acid when adding water; Helps in hydrolysis and is not so viscous.

LDPE is slowly soluble in tetrahydronaphthalene or decahydronaphthalene, and polypropylene needs to be heated to dissolve insoluble in general organic solvents.
