聚乙烯-聚异戊二烯两嵌段共聚物的合成和表征
摘要:
以正丁基锂为引发剂,阴离子聚合合成了聚丁二烯-聚异戊二烯两嵌段共聚物,然后以2-乙基己酸钴/三乙基铝配位络合催化体系,将其中丁二烯段进行选择性氢化,制备了聚乙烯-聚异戊二烯两嵌段共聚物.对这两种嵌段产物分别用红外光谱、GPC,粘度法、DSC、X-射线衍射和动态力学谱等方法进行了表征.

SYNTHESIS AND CHARACTERIZATION OF POLYETHYLENE-b-POLYISOPRENE DIBLOCK COPOLYMERS
Abstract:
Polybutadiene-b-polyisoprene diblock copolymer(PB-b-PI) was synthesized using anionic polymerization initiated by n-butyllithium.PB segment in it was then uniquely hydrogenated in the presence of cobalt 2-ethylhexanoate/triethylaluminium catalyst,giving poly ethylene-b-polyisoprene diblock copolymer(PE-b-PI).The two diblock copolymers were characterized by infrared analysis,GPC,viscosity,DSC,x-ray diffraction and dynamic mechanical measurements.
