Abstract

Inventia se refera la un procedeu de separare a cauciucului cis-1,4-polibutadienic din solutia de polimer, prin desolventarea cu apa, care, în scopul prevenirii aglomerarii particulelor din cauciuc, în procesul separarii, se realizeaza desolventarea în prezenta unei cantitati de 0,1+1 g/100 g cauciuc dintr-o alchiletoxibetaina cu formula (vezi formula in desc.= în care R este radical de hidrocarbura saturata C12.....C14, R2, R3 radical metil, n=1.3 de preferinta 3.The invention relates to a process for separating cis-1,4-polybutadiene rubber from the polymer solution by water desolvation which, in order to prevent the agglomeration of the rubber particles in the separation process, is carried out in the presence of a quantity of 0 , 1 + 1 g / 100 g of rubber of an alkylethoxytetine of the formula (see the formula in which R is saturated hydrocarbon radical C12 -C14, R2, R3 methyl radical, n = 1.3 preferably 3 .
