Physics students learn polymer chemistry question 10

I am a polymer major, and I will tell you very clearly: polymer chemistry basically has little to do with high school chemistry. Organic chemistry courses are offered during college, and the content is much more detailed than that of high school (including the knowledge part of organic chemistry in high school).

Support your choice

Feel free to use materials science and engineering though with polymer chemistry.

But polymer chemistry is not difficult, just be patient.

It's easy to grasp the characteristics and find the pattern.

It's much simpler than the laws of physical motion.

At the beginning of the polymer major, we should first learn the four major chemistry, inorganic, organic, differentiation, and physicochemical, and then the professional course of polymer, and it is very important to learn polymer organic chemistry, especially in the future to engage in scientific research. But you have to rely on yourself for everything, and everyone can do well in the cross-professional postgraduate examination, as long as you work hard, you can learn everything well.

I think it's not important to choose courses, the important thing is that you choose what you are interested in, although chemistry in high school is the foundation, but as long as you are down-to-earth in your later studies, there is nothing bad to learn seriously, you must first believe in yourself, I can!! You can learn well, don't worry about anything, be brave and choose!

1. Polymer chemistry and polymer physics, as long as you learn seriously and hard, it is not difficult.

2. Polymer chemistry is an emerging comprehensive discipline that studies the synthesis, chemical reaction, physical chemistry, physics, processing and application of polymer compounds. The history of synthetic polymers is only 80 years, so it is less than 60 years since polymer chemistry has really become a science, but it has developed very rapidly. At present, its content goes beyond the scope of chemistry, so it is now more logical to refer to this discipline by the term polymer science.

Polymer chemistry in the narrow sense refers to polymer synthesis and polymer chemical reactions. In fact, human beings have been closely related to polymers from the very beginning, and the animals and plants in nature, including the human body itself, are composed of polymers as the main components, and these polymers have long been used as raw materials to manufacture production tools and means of life.

3. Polymer physics is the science that studies the physical properties of polymer substances. The main research directions include thermodynamics and statistical mechanics such as polymer morphology, polymer mechanical properties, polymer solutions, polymer crystallization, and kinetic disciplines such as polymer diffusion.

It doesn't feel like there's any point in asking such questions.

It is advisable to look at the book and check the information.

Polymer physics is simply written, and the physical chemistry teacher forgets it when he talks about it.

Ask the first question 3:

The decrease in molecular weight after the addition of ethanol should be due to the relatively high finger shift constant of ethanol chain transfer, which acts as a molecular weight regulator and thus reduces the molecular weight.

When the amount of ethanol is increased to a certain proportion, the reaction of the number of acres of polyhand is carried out in the undesirable solvent or non-solvent, and there is an obvious automatic acceleration phenomenon, resulting in a higher molecular weight of the product than the bulk polymerization.

This needs to be checked for professional books, and I forgot it all in two years.

The professionalism is relatively strong, so it is recommended to ask a professional teacher.

You can refer to the reaction mechanism.

Anode: Cu+ +e=cu potential e=

Cathode: 2H2O+2E=H2+2OH- Electric potential e=theoretically change the voltage required by the electrolytic reaction e=

Cu2+ +2E=Cu potential E=, voltage E=Considering that polarization should occur in the actual electrode process, the voltage should be greater than that, and the general control of about 2V can avoid the conversion of Cu+ into Cu2+, and the voltage cannot be lower, so the electrolytic voltage range is.

Only experiments can be determined, and results cannot be calculated.

It is a comprehensive discipline in processing and forming, application and other aspects.

The structural characteristics of polymers are: there are a lot of atoms in the molecule, and polymer chemistry is the study of the synthesis, chemical reaction, physical chemistry, and physics of polymer compounds, and is connected by chemical bonds, so the molecular weight is very large; Polymers can be divided into synthetic polymers and natural polymers. Animals and plants in nature are composed of polymers as the main components, and the main foods of human beings such as starch and protein.

Polymer Chemistry and Physics is an important professional basic course for all majors of polymer science, which lays a theoretical foundation for subsequent courses such as polymer processing principles, polymer synthesis technology, and other polymer courses.
