Polymer materials refer to materials based on polymer compounds. Polymer materials are materials composed of compounds with high relative molecular weight, including rubber, plastics, fibers, coatings, adhesives, and polymer matrix composites. The unique structure, easy modification and easy processing characteristics of polymer materials make it have incomparable and irreplaceable excellent properties of other materials, so they are widely used in science and technology, national defense construction and various fields of national economy.

Before the polymer material is processed, it is synthesized to synthesize the monomer into a polymer for granulation, and then it is melt processed. The synthesis methods of polymer materials include bulk polymerization, suspension polymerization, emulsion polymerization, solution polymerization and gas phase polymerization. Among them, initiators play a very important role, azo initiators and peroxide initiators are commonly used initiators, and polymer material additives often play an obvious role in improving the performance of polymer materials and reducing costs. >>>More
For example, gel intelligence can be applied to the medical field.
When polymer materials are heated in the air, they will decompose to form volatile combustibles, which can be burned when the concentration of combustibles and the temperature of the system are high enough. Therefore, the combustion of polymer materials can be divided into two processes: thermal and oxygen degradation and combustion, involving heat transfer, thermal and oxygen degradation of polymer materials in the condensed phase, diffusion of decomposition products in the solid phase and gas phase, mixing with air to form an oxidation reaction field and chain combustion reaction in the gas phase. When the heat source heat of the polymer material can decompose the polymer material, and the combustibles produced by the decomposition reach a certain concentration, and the system is heated to the ignition temperature, combustion can occur. >>>More
You can go to relevant professional enterprises and factories to do process, sales, quality, product research and development, I am personally a polymer professional, now I am a process engineer, and I have also done product research and development (product engineers do it) for a period of time, or go to technology, it is best to ug and so on, it is relatively easy to find a job.
This problem is too big, polymer materials are mainly divided into plastics, rubber, coatings, fibers, adhesives, and special polymers. Employment is mainly in these aspects. Take a look at my previous analysis of direction.
