ARTICLE ANNOTATION

quote
It is known that polyvinyl chloride, along with polyethylene and polypropylene, is the most important cheap construction polymer with a large tonnage. Therefore, the amount of its waste is constantly increasing. is the main method of protection. One of the ways to solve this problem is the chemical modification of PVC through polymer transformations. This review discusses the modification processes of PVC with carbamide and thiocarbamide.
