Abstract
изобретение относитс к получению блоксополимеров на основе линей . ных полиамидов и низкомолекул рньтх полибутадиеновых каучуков. Изобретение позвол ет увеличить морозостойкость сополимеров и снизить ге- леобразование при синтезе за счет того, что в способе получени блок- сополимеров путем поликонденсацин при нагревании лактамов низкомолекул рных олигобутадпенои с концевыми карбоксильными группами при их массовом соотношении (80-95):(5- 20) соответственно, в присутствии полиамидообразующей добавки в количестве 4-15 мас.% в расчете на суммарное количество лактама и олиго- диена, и воды в качестве поли амид ооб- раэующей добавки используют соль ади- пиновой кислоты и гексаметиленди- амина, а воду используют в количестве 6-25 . в расчете на суммарное/ количество лактама и олигодиена, 1 табл., (Л сThe invention relates to the production of linear block copolymers. polyamides and low molecular weight rnh polybutadiene rubbers. EFFECT: invention makes it possible to increase the frost resistance of copolymers and to reduce gelation during synthesis due to the fact that in the method for producing block copolymers by polycondensacin by heating lactams of low molecular weight oligobutadpenoins with terminal carboxyl groups at their mass ratio (80-95) :( 5-20 ) respectively, in the presence of a polyamide-forming additive in an amount of 4-15 wt.% based on the total amount of lactam and oligodien and water, an adipic acid salt is used as a poly amide-forming additive and you geksametilendi- amine, and water is used in an amount of 6-25. calculated on the total / amount of lactam and oligodien, 1 tab., (L s
