Results show that the copolymer consists of two-phases with PS microdomains several hundred A in size dispersed in EPR rubber matrix. The mierodomains change in shape from spheric to rod-like as PS-content in the copoly-mers increases. Small amount of EPR-g-PS in EPS+PS blends acts as an "emulsifier", making the microdomains in the blends smaller and the dispersion more homogeneous. Multi-transition behavior of the copolymers confirms the existence of separated phases. %U http://www.alljournals.cn/get_abstract_url.aspx?pcid=6E709DC38FA1D09A4B578DD0906875B5B44D4D294832BB8E&cid=6579068328FE643F&jid=15971983683C7643EE80F1CE621DEB60&aid=F515E8708104F2AE&yid=74E41645C164CD61&iid=38B194292C032A66&sid=2BA123C6EB9D54C2&eid=BC084ACE66B62CC8&journal_id=1000-3304&journal_name=高分子学报&referenced_num=0&reference_num=0
