Abstract:
A monomer, oligomer or polymer of formula (I) or (II); where: formula (I) is denoted by in which:A1 is selected from the group consisting of: polyester blocks having a molecular weight of between 250 and 10,000; polyurethane blocks having a molecular weight of between 500 and 5000; hydrocarbon-comprising back-bones of a mono- or polycarboxylic acid; and addition products of a polycarboxylic acid and of a cyclo-aliphatic diepoxide; m is a number from 1 to 6, R1 is a cycloaliphatic group carrying a hydroxyl group situated in the &agr; position with respect to the oxygen atom to which R1 is bonded and where R1 may be further substituted or unsubstituted; R2 is a second cycloaliphatic group carrying an oxirane group situated at the chain end and where R2 may be further substituted or unsubstituted; and B is selected from the group consisting of: one or more covalent bonds; on oxygen atom; linear, branched or cyclic hydrocarbon-comprising radicals which may be unsubstituted or substituted by one or more oxygen and/or silicon atoms; and formula (II) is denoted by: in which:A2 is a block selected from the group consisting of: homopolymers and copolymers of at least one vinyl monomer; n is an integer from 0 to 15, with the condition that n is at least equal to 1 when Y is sulphur; Y is selected from the group consisting of: a sulphur atom; â€”CRâ€²Râ€³ radicals, in which Râ€² and Râ€³ are each an aliphatic group having from 1 to 4 carbon atoms; and mixtures thereof; q is an integer or non-integer ranging from about 1 to about 2; and R1, B and R2 are defined as in the above formula (I).
