Abstract:
A ring-opened polymer prepared by reacting at least one pericyclic olefin selected from the group consisting of formulae (I) and (II) through ring-opening metathesis polymerization ##STR15##whereinA and B are the same or different and are independently selected from the group consisting of halogen, hydrogen, C.sub.3-20 cyclic or pericyclic alkyl, C.sub.1-20 linear and branched alkyl, C.sub.6-20 aryl, C.sub.7-20 arylalkyl, C.sub.7-20 alkylaryl, silyl, alkylsilyl, germyl, alkylgermyl, alkoxycarbonyl, acyl, and a heterocylic group; or, A and B are linked together to form a C.sub.3-20 saturated or unsaturated cyclic hydrocarbon group or a substituted or unsubstituted heterocyclic group;C is selected from the group consisting of oxygen, sulfur, ##STR16##--CH.sub.2 --, and --SiH.sub.2 --,wherein each R.sup.1 is independently selected from C.sub.1-20 alkyl and phenyl;each R is independently selected from hydrogen, halogen, and C.sub.1-20 alkyl; andeach n is an integer from 1 to 6.
