FIELD: polymer materials. SUBSTANCE: availability in copolymers of units of vinylglycidyl ether of ethylene glycol, alkyl vinyl ethers, and vinyloxyethyl ether of glycerol gives rise to improved heat resistance, solubility, adhesion, and strength of coatings manufactured on the basis of prepared copolymers. Content of epoxy groups in copolymers ranges from 2.19 to 3.87 wt %. Makeup of water phase for suspension and emulsion copolymerization is similar to those used in industrial production of polyvinylchloride. EFFECT: improved characteristics of coating based on copolymers. 3 tbl, 24 ex
