CHARACTERIZATION AND PROPERTIES OF (BUTADIENE- ETHYLENE OXIDE) MULTIBLOCK COPOLYMERS
(丁二烯-环氧乙烷)多嵌段共聚物的表征及性能

Multiblock copolymers of butadiene and ethylene oxide prepared by coupling of telechetic hydroxyl polybutadiene and polyethylene glycol with toluene diisocyanate were purified, characterized and their emulsifying, phase transfer catalytic and mechanical properties were studied.
