Abstract:
A coating composition comprising:(a) a polymer having a number average molecular weight of about 30,000 or below comprising at least one exomethylene lactone or lactam monomer of the structure: where X&boxH;0 or Nâ€”R7, n=0, 1 or 2 and R1, R2, R3, R4, R5, R6, R7 are independently selected from the group (I) consisting of H, â€”CH(O), â€”CN and halogen, and from the group (II) consisting of â€”C(O)OR9, â€”C(O)NR10R11, â€”CR12(O), â€”C(O)OC(O)R13, â€”C(O)NR14COR15, â€”OC(O)R16, â€”OR17, â€”NR18R19 alkyl, substituted alkyl, aryl and substituted aryl; wherein when R1, R2, R3, R4, R5, R6, R7 are selected from group (II), they may optionally form a cyclic structure with one another; R9, R10, R11, R12, R13, R14, R15, R16, R17, R18 and R19 are H, alkyl, aryl, substituted alkyl or substituted aryl; R17 is alkyl, aryl, substituted alkyl or substituted aryl; and wherein the alkyl and substituted alkyl are C1-C12; and(b) at least one other compolymerizable monomer.
