Синтез водостойких и биостойких поливинилацетатных дисперсий

Abstract

The possibility of the joint use of water resistance and biostable modifiers during synthe-sis of polyvinyl acetate dispersion was determined. We obtained samples of polyvinyl acetate dispersion containing 0.5 wt.% TiO2, SiO2, polyhexamethyleneguanidine hydrochloride (PHMG), both individually and together. In the course of the work, it was established that the modification of dispersion samples with PHMG + TiO2 and with PHMG + SiO2 makes it possible to obtain compositions that simultaneously gains enhanced biostability and water resistance.
