Abstract:
A thermally curable polymer composition comprising a hydroxyl-containing polymer, a polyfunctional epoxide cross-linking agent and optionally a thermal acid generator, wherein said hydroxyl-containing polymer comprises (a) at least one monomer unit selected from the group consisting of: cyclohexanol, hydroxystyrene, hydroxyalkyl acrylate or methacrylate, hydroxycycloalkyl acrylate or methacrylate, hydroxyaryl acrylamide or methacrylamide, and allyl alcohol and (b) a monomer unit of a cycloaliphatic ester of acrylic acid or methacrylic acid; provided that when a phenolic monomer is not present in an amount of at least about 10 mole % of said hydroxyl-containing polymer, said thermal acid generator is present and wherein the thermal acid generator has the general structure: where R7 is a substituted or unsubstituted alkyl, cycloalkyl or aromatic group wherein the substituted group is a halogen, alkoxy, aromatic, nitro or amino group; and R8 to R12 are independently selected from a hydrogen, a linear or branched C1 to C4 alkyl, an alkoxy, an amino, an alkylamino, an aryl, an alkenyl, a halogen, an acyloxy, a cycloalkyl, or an annulated cycloalkyl, aromatic or heterocyclic.
