Abstract

Inventia se refera la un procedeu de obtinere a copolimerilor acrilici filabili care, în scopul cresterii gradului de conversie si asigurarii uniformitatii polidispersiei, se supune copolimerizarii amestecul de comonomeri în prezenta unui sistem cat alitic redox persulfat de potasiu, bisulfit de sodiu, sulfat feros, apa de reactie acidulata astfel încât raportul persulfat de potasiu/monomer sa fie 5,5 ... 7,5 kg/t de preferat 6 ... 7 kg/t, iar raportul Fe+ la puterea 2/monomer sa fie 3 ... 6 kg/t, de preferat 4 ... 5 kg/t, concentratia reactantilor fiind de 11 ... 20%, de preferinta 15 ... 18%, iar timpul de reactie de 35 ... 50%, de preferinta 38 ... 43 min.
