The dependence of the viscosity of adhesives, such as polyurethane and polychlororpene, on polyvinyl acetate (PVAc) content has been studied. This PVAc with high Tg and good dimensional stability was obtained as waste in process of polyvinyl acetate emulsion production. Low content of PVAc (2-3wt%) significantly increases the adhesives viscosity. The changes in the viscosity are accompanied by the changes in morphology and in the adhesion and cohesion properties. It is shown that PVAc is active polymer-modifier towards polyurethane adhesive, but inert towards polychloroprene.
