Abstract
Monomers of the formulae: ##STR1## as well as polymers and copolymers thereof wherein n=2-20; R=H, CH.sub.3 or CHOHR' where R'=straight-chain or branched alkyl, optionally substituted by hydroxyl, alkoxy or ester substituents, straight-chain, branched or cyclic alkenyl, aryl, optionally substituted by halogenated, nitro or alkoxy substituents, unsaturated heterocycle, alkylaryl and arylalkyl, R=CH.sub.3 in formula (I) in the case of monomers and homopolymers wherein n=2 and in the case of monomers wherein n=4.
Claims4
An acrylic or methacrylic compound of the formula:
- ##STR24## wherein:
- n is an integer ranging from 2-20 inclusive, and
- R is a hydrogen atom, methyl or CHOHR', wherein R' is a straight-chain or branched alkyl optionally substituted by hydroxyl, alkoxy, or ester substituents;
- straight-chain, branched, or cyclic alkenyl;
- aryl radicals optionally substituted by halogen, nitro, or alkoxy;
- unsaturated heterocyclic radicals;
- alkylaryl;
- or arylalkyl radicals, with the proviso that R does not represent methyl in the formula (I) when n is 2 or 4.
