CYCLOPOLYMERISATION MONOMERS AND POLYMERS

摘要

Compounds of general formula (I) characterised in that R<1> and R<2> are independently selected from the group consisting of COOR, CN, aryl, substituted aryl, COOH, halogen, C(O)NHR<4>, C(O)NR<5>R<6>; X and Y are independently selected from the group consisting of H, COOH, COOR, CN, R<3>CO-, C(O)NHR<4>, C(O)NR<5>R<6>, P(O)(OR<7>)2 and SO2R<8>; with the proviso that X and Y are not both H when R<1> and R<2> are both COOCH3 or both phenyl; or X and Y together with the carbon atom to which they are attached form a carbocyclic or heterocyclic ring system which may contain oxygen, sulfur or nitrogen atoms; and R, R<3>, R<4>, R<5>, R<6>, R<7> and R<8> are various groups. Polymers and copolymers derived from such compounds.
