TEM showed that the phase inversion of PU(HTPB)/PSt-IPN occurred in the concentration of 25% PU(HTPB), and the size of dispersed phase domains of the IPN formed was smaller in the concentration about 50% PU(HTPB). Increasing DVB content or proportion of NCO to OH enhanced in-terpenetration of two components. All of IPN samples exhibited special cellular structure. According to the fact that PU(HTPB) was formed first,a formation mechanism of the struc-ture was proposed. %K 聚氨酯 %K 聚苯乙烯 %K PMMA %K IPN %U http://www.alljournals.cn/get_abstract_url.aspx?pcid=6E709DC38FA1D09A4B578DD0906875B5B44D4D294832BB8E&cid=6579068328FE643F&jid=15971983683C7643EE80F1CE621DEB60&aid=C71650CF9C10407BB976F675980DE146&yid=1833A6AA51F779C1&iid=94C357A881DFC066&sid=E6A0A363CA4FC5CF&eid=F8AEC975DBDD7F2F&journal_id=1000-3304&journal_name=高分子学报&referenced_num=0&reference_num=1
