Сополимеризация индена с дициклопентадиеном под действием каталитической системы (с 2Н 5) 2AlCl–TiCl 4

Сополимеризация индена с дициклопентадиеном под действием каталитической системы (с 2Н 5) 2AlCl–TiCl 4

Abstract

The authors have studied dicyclopentadiene copolymerization with indene in toluene solution under the catalytic system (С 2Н 5) 2AlCl–TiCl 4. It has been ascertained that in this case the sequence copolymer is formed and dicyclopentadiene is more active monomer in the mixture. The conclusion is made that at dicyclopentadiene indene ratio 0,55:0,45 (it corresponds to azeotropic point on copolymer composition curve) the molecular weights of copolymers as well as heat generation in the system depend extremally on dicyclopentadiene content in copolymer.

Исследована сополимеризация дициклопентадиена и индена в растворе толуола под действием каталитической системы (С 2Н 5) 2AlCl–TiCl 4. Установлено, что в этом случае образуется чередующийся сополимер, причем более активным мономером в смеси является дициклопентадиен. Сделан вывод о том, что при соотношении дициклопентадиена к индену, равному 0,55:0,45, что соответствует азеотропной точке на кривой состава сополимера, молекулярные массы сополимеров, а также тепловыделение в системе экстремально зависят от содержания дициклопентадиена в сополимере.
