Abstract

Inventia de fata se refera la un procedeu de obtinere a unei dispersii apoase pe baza de copolimer stiren-acrilo-maleic prin copolimerizarea unui amestec de monomeri constituit din 25...35 parti în greutate de stiren, 15...25 parti în greutate maleat de di-2-etilhexil, 1...5 parti în greutate acrilonitril, 1...4 parti în greutate acid acrilic în 40,5...46 parti în greutate apa, în prezenta unui cuplu de emulgatori constituit din 0,5...3 parti în greutate sare de sodiu semiesterului sulfosuccinic cu nonilfenol etoxilat cu 6 moli etilenoxid si 0,2...1 parti în greutate nonilfenol etoxilat cu 16 moli etilenoxid si 0,3...1 parti în greutate persulfat de postasiu drept initiator de polimerizare, utilizabil ca liant în vopselele emulsionate cu efect decorativ pentru constructii, vopsele anticorosive si altele.The present invention relates to a process for obtaining an aqueous dispersion based on styrene-acrylic maleic copolymer by copolymerizing a mixture of monomers consisting of 25 ... 35 parts by weight of styrene, 15 ... 25 parts by weight diethyl ether, 2-5 parts by weight of acrylonitrile, 1-4 parts by weight of acrylic acid in 40.5 ... 46 parts by weight of water, in the presence of a couple of emulsifiers composed of 0 , 5 to 3 parts by weight of the sodium salt of sulfosuccinic semester with nonylphenol ethoxylated with 6 moles of ethylene oxide and 0.2 to 1 part by weight of nonylphenol ethoxylated with 16 moles of ethylene oxide and 0.3 to 1 part by weight of persulfate as an initiator of polymerization, usable as a binder in emulsified dyes for decorative building, anti-corrosive paints and the like.
