Abstract
Inventia de fata se refera la un procedeu de obtinere a cauciucului sintetic polietilencloruslfonat prin tratarea polietilenei în solutie de vclor si dioxid de sulf sau clor si SO2Cl2, în prezenta de initiatori radicalici cunoscuti la care se adauga o proportie de 0,03...2% fata de polietilena, un fosfit ales dintre trifenifostit sau octofenilfosfit de pentaeritrita, iar la faza de izolare a polimerului se adauga o proportie de 0,01...1,00% fata de apa desolventare, un polifosfat de metal alcalin ales dintre hexametafosfat de sodiu sau trimetafosfat de sodiu. se obtine un polimer cu proprietati fizico-mecanice îmbunatatite, cu o productivitate marita.
