ELASTOMERIC HYBRID NETWORKS FROM RUBBERS AND BIFUNCTIONAL POLYOLEFINS

Two-component networks were prepared by ''ene'' reaction of azodicarbo xylate-terminated polyolefins with cis-1,4-polyisoprene (IR), natural rubber (NR) and cis-1,4-polybutadiene (BR). Thermal and dynamic mechan ical Properties of the networks were investigated. The results suggest ed that the reaction of: end-functionalized polyolefin with IR or NR w as effective for the preparation of elastomeric hybrid networks consis ting of their immiscible polymer pairs. In contrast, phase separation of BR segments was observed in polyolefin-linked-BR network.
