Abstract

In experimental course of polymer chemistry

a free radical polymerization for the preparation of high molecular weight polyacrylamide in aqueous solution through the method imitating the industrial process could be adopted. The preparation is carried out under high monomer dose

non-thermostatic

non-stirring condition using the combination of redox initiator

azo initiator and peroxide initiator. The aqueous free radical polymerization has the advantages of low energy consumption and high efficiency. This practical experiment will be beneficial to the students for their broadening knowledge and better understanding of curse knowledge. Meanwhile

it is also useful to train the students with good environmental protection and energy-saving awareness

the ability to integrate theory with practice.
