Claims20
An article of manufacture comprising a polymer compound of a formula
- wherein R is a C(O)C(R1)(R2) moiety, where R1 and R2 is independently selected from H, alkyl and substituted alkyl;
- R′ is selected from C(O)C(R′1)(R′2), C(R′3)(R′4) and covalent bond moieties, where R′1 and R′2 is independently selected from H, alkyl and substituted alkyl, and R′3 and R′4 is independently selected from alkyl and substituted alkyl;
- R″ is selected from alkyl, substituted alkyl, phenyl, substituted phenyl, aryl and substituted aryl moieties;
- X is selected from alkyl, substituted alkyl, phenyl, substituted phenyl, aryl, and substituted aryl moieties;
- m and m′ are integers selected from 0 and 1, provided one of m and m′ is 0 when the other is 0;
- and n is selected from 1 and integers greater than 1.
