Abstract
Inventia se refera la un procedeu de obtinere a policlorurii de vinil pentru paste pentru polimerizarea sau copolimerizarea în emulsie a clorurii de vinil în prezenta de initiatori hidrosolubili; polimerizarea are loc în faza apoasa în prezenta unui complex de aditie activ obtinut prin reactia dintre alcooli grasi superiori, saturati sau o tensida ionica, în care raportul între alcooli si tensida este 1:1...6:1, cantitatea fata de monomer este de 0,6...2%, iar cea de tensida de 0,25...0,6% si în prezenta unei tenside neionice reprezentata de alcooli grasi superiori etoxilati cu 12...18 atomi de carbon, cu grad de etoxilare 10...40, nonilfenol etoxilat cu acelasi grad de etoxilare, în proportie de 0,5...2% raportat la monomer la un raport faza apoasa/monomer de 1,1...3 si la un pH de 7...8 realizat cu fosfat trisodic, la temperaturi cuprinse între 30m/min.
