    • The present invention provides a ring-opened polymer, which is prepared by reacting at least one pericyclic olefin elected from those represented by formulae (I) and (II) through ring-opening metathesis polymerization wherein A and B may be the same or different and are independently selected from the group consisting of halogen, hydrogen, C3-20 cyclic or pericyclic alkyl, C1-20 linear and branched alkyl, C6-20 aryl, C7-20 arylalkyl, C7-20 alkylaryl, silyl, alkylsilyl, germyl, alkylgermyl, alkoxycarbonyl, acyl, and a heterocylic group; or, A and B are linked together to form a C3-20 saturated or unsaturated cyclic hydrocarbon group or a substituted or unsubstituted heterocyclic group; C is selected from the group consisting of oxygen, sulfur,  —CH2—, and —SiH2—, wherein each R1 is independently selected from C1-20 alkyl and phenyl; each R is independently selected from hydrogen, halogen, and C1-20 alkyl; and each n is an integer from 1 to 6.
    • 本发明提供一种开环聚合物,其通过使由式(I)和(II)表示的那些所选择的至少一种环氧烯烃通过开环易位聚合反应制备,其中A和B可以相同或不同,并且独立地 选自卤素,氢,C 3-20环状或环脂族烷基,C 1-20直链和支链烷基,C6-20芳基,C7-20芳基烷基,C7-20烷基芳基,甲硅烷基,烷基甲硅烷基,甲基,烷基锗烷基,烷氧基羰基 ,酰基和杂环基团; 或者A和B连接在一起形成C3-20饱和或不饱和环状烃基或取代或未取代的杂环基; C选自氧,硫,-CH 2 - 和-SiH 2 - ,其中 每个R 1独立地选自C 1-20烷基和苯基;每个R独立地选自氢,卤素和C 1-20烷基; 而且n是1到6的整数。
