Abstract

Inventia se refera la un procedeu de obtinere a cauciucului siliconic cu vulcanizare la temperatura camerei, care, în scopul obtinerii unor elastomeri cu masa moleculara cuprinsa între 45000 si 105000, supun policondensarii ciclurile dimetilsiloxanice, în prezenta acidului sulfuric, a carui concentratie variaza între 15 si 35%, timp de 2 h.
