Keywords:
PVC, modification, urea, anionite.Abstract
It is known that polyvinyl chloride, along with polyethylene and polypropylene, is the most important large-tonnage cheap construction polymer. For this reason, the amount of its waste is constantly increasing. One of the ways to solve this problem is the chemical modification of PVC through polymer transformations. This review discusses the conditions for synthesizing anionite by modifying PVC with urea. As a result of the study of the influence of various external factors on the modification of polyvinyl chloride with urea in the production of anionites, the optimal conditions for the modification of polyvinyl chloride with modifiers were determined, the optimal mass ratio of polymer and modifier was 1:5 mass ratio, the optimal temperature of the reaction medium was 433 K, respectively for the synthesis of PPE-2 , the acceptable time for the duration of the modification was set to 8 hours.
