Abstract

1. Способ получения низкомолекулярных полимеров по авт.св. 1267768, отличающийся тем, что, с целью снижения цветности пленкообразующего на основе низкомолекулярных полимеров, диеновый каучук или отходы его производства перед термоокислительной деструкцией обрабатывают в растворителе алифатической насыщенной дикарбоновой кислотой, взятой в количестве 0,5 - 1,5 мас. ч. в расчете на 100 мас.ч. каучука, при 80 - 100С в течение 2 - 3 ч.2. Способ по п.1, отличающийся тем, что в качестве кислоты используют щевелевую, малоновую, янтарную кислоты.1. The method of obtaining low molecular weight polymers by ed.St. 1267768, characterized in that, in order to reduce the color of the film-forming material based on low molecular weight polymers, the diene rubber or its production waste is treated with aliphatic saturated dicarboxylic acid in an amount of 0.5 - 1.5 wt. Before thermo-oxidative destruction. hours per 100 wt.h. rubber, at 80 - 100C for 2 - 3 h.2. The method according to claim 1, characterized in that the quality of the acid used is shallow, malonic, succinic acid.
