Abstract

Inventia se refera la un procedeu pentru evitarea depunerilor de cruste în procesul de polimerizare a monomerilor vinilici, prin acoperirea suprafetelor care vin în contact cu reactantii cu o solutie continînd (A) un colorant si un pigment, (B) un compus aromatic sau heterociclic avînd cel putin 5 legaturi conjugate pi si, eventual, un compus anorganic, un agent de fixare constînd dintr-un polimer, apoi stratul de acoperire astfel format este uscat, dupa care are loc procesul de polimerizare, iar concentratia de ioni de clor din amestecul de reactie este reglata astfel încît sa nu fie mai mare decît 100 ppm.
