Abstract
Procedeul de obtinere a unor dispersii apoase de copolimeri pe baza de acetat de vinil, consta în copolimerizarea în emulsie apoasa a unui amestec de monomeri constituiti din 50-70% acetat de vinil, în greutate de 25-45% malet, fumarat sau itaconat de dibutil sau dioctil, 0,1 saturat ales dintre acid acrilic, acid metacrilic sau crotonic si 0,1...4% un monomer acrilic functional ales dintre, acrilat de glocodil, metacrilat de glicidil sau N-metilolacrilamidî în prezenta a 1..8% în greutate raportat la total monomeri format unui cuplu de emulgator constituit dintr-un emulgator aniodic de tipul sare disodica a monoesterului.The process for obtaining aqueous dispersions of copolymers based on vinyl acetate consists in copolymerising in aqueous emulsion a mixture of monomers consisting of 50-70% vinyl acetate, weighing 25-45% maleate, fumarate or itaconate dibutyl or dioctyl, 0.1 saturated by acrylic acid, methacrylic acid or crotonic acid and 0.1 to 4% of a functional acrylic monomer selected from glycidyl acrylate, glycidyl methacrylate or N-methylolacrilamide in the presence of 1. 8% by weight based on the total monomers formed by an emulsifier couple consisting of an anionic emulsifier of the disodium salt type of the monoester.
