| 摘要 |
The present invention provides a cyclic dione polymer, which is a homopolymer or a copolymer of a cyclic dione monomer selected from those represented by formulae (I) and (II)whereinA 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,wherein each R1 is independently selected from C1-20 alkyl and phenyl. |
