Abstract
Inventia se refera la un procedeu pentru polimelizarea în suspensie a clorurii de vinil în mediu apos, continand un agent tensioactiv neionic si în prezenta unui initiator de polimerizare solubil în monomer, care sonsta în aceea ca în mediul de polimerizare se introduce o cantitate de 0,01..2 parti în greutate fata de 100 parti monomer, un agent de reticulare avand formula generala : CH2=CR-CH2-(O-CH2)P-(-O-CH2-CHME)q-(-O-CH2-CHEt)r-O-CH2-CR=CH2 în care Me reprezina o grupa metil, Et este o grupa etil, R este un atom de hidrogen sau o grupa metil, p, q si r sunt fiecare zero sau un numar întreg pozitiv, cu mentiunea ca p+q+r sa fie mai mic de 500, adaugarea facandu-se în întregime la o conversie a monomerului de 1..20% sau în portiuni, prima portiune în cantitate de 1..30% adaugandu-se înainte de începerea reactiei de polimerizare iar restul într-o a doua portiune la o conversie a monomerului de 1..20%.
