Patent ID: 8124701

Claim:
Monomers represented by formulae (I) or (II): wherein R 1 is hydrogen or C 1-3 alkyl, R 2 is hydrogen, methyl, linear or branched C 2-30 alkyl, where said C 2-30 alkyl is optionally interrupted by O, S or Si, and is optionally further substituted by phenyl, OR 3 , COOR 4 or NR 5 R 6 ; X is methylene or linear or branched C 2-30 alkylene, optionally substituted by one or more phenyl, wherein C 2-30 alkylene is optionally interrupted by O or S; p is 1, 2, 3 or 4; when p is 1, R is hydrogen, methyl, linear or branched C 2-30 alkyl, cycloalkyl, C 2-30 alkenyl, aryl, aralkyl, heterocycloalkyl or heterocycloaryl, wherein the alkyl or alkenyl is optionally interrupted by O or S, and is optionally further substituted by one or more, OH, C 1-16 alkyl, phenyl, OR 3 , COOR 4 or NR 5 R 6 ; when p is 2, 3 or 4, R is a di-, tri- or tetra-valent linking group, said linking group is a polymer, methylene, linear or branched C 2-20 alkylene, cycloalkylene, linear or branched C 2-30 alkenylene, arylene, aralkylene, heterocycloalkylene or heterocycloarylene, the C 2-30 alkylene or C 2-30 alkenylene is optionally interrupted by O or S, and the aryl or the arylene group, the aryl of the aralkyl, the cycloalkylene, the heterocycloalkylene or heterocycloarylene is optionally further substituted by one or more halogen, OH, C 1-4 haloalkyl, C 1-16 alkyl, substituted or unsubstituted phenyl, OR 3 , COOR 4 or NR 5 R 6 ; R 3 is linear or branched C 1-10 alkyl or phenyl; R 4 is linear or branched C 1-10 alkyl or phenyl; and R 5 and R 6 are independently hydrogen, linear or branched C 1-10 alkyl, or R 5 and R 6 together form a ring.
