In the past 40 years

China's higher education has been greatly developed because of the reform and opening up. And the experimental instruments and equipment in colleges and universities have become more and more advanced and complete. However

the experimental content in colleges and universities still stays at the level of compilation in the 1980s and 1990s. Compared with the current development of science and technology as well as the experimental technology

our experimental content lags behind. Even more puzzling was the fact that some graduate students in engineering colleges have not yet set up higher experimental courses. Therefore

how to make the universities in our country from big to strong and so as to completely improve the comprehensive experimental ability and scientific research ability of graduate students has become the biggest bottleneck restricting the development of higher education in our country. In this paper

two classical synthesis experiments of polymer chemistry

free radical chain polymerization and step polymerization

are analyzed in detail. The integration of polymer chemistry experiment and polymer physics experiment is very important to improve the comprehensive experimental ability and research ability of college students

especially for the graduate students. So the students can firmly grasp the main line including experimental synthesis of polymer materials

molecular weight determination

chemical structure characterization and properties testing

et al. It is to make students master as many as possible knowledge such as viscosity method or gel permeation chromatography (GPC) method for molecular weight test

Malvin Laser instrument for particle size analyzer and particle size distribution test

infrared spectrometer and scanning electron microscope test methods

and the analysis methods of thermal properties

electrical properties and mechanics performance et al.

so that the students can know the whole leopard over seeing a spot. At last

this paper could provide reference and promotion for comprehensively improving the experimental ability and scientific innovation ability of graduate students.
