Abstract:
Monomer compound, characterized in that it corresponds to the formula: ##STR105##in which Z represents H or CH.sub.3 and X represents O or S, andwhen X represents S, Y is a radical of formula: ##STR106##where R.sup.1 and R.sup.2 are chosen from H, alkyl radicals, or alternatively R.sup.1 and R.sup.2 together form a --(CH.sub.2).sub.5 -- radical and n.sub.1 is an integer from 0 to 2 inclusive, andwhen X represents O, Y is the radical (a) defined above or a radical chosen from the radicals of formulae: ##STR107##in which n.sub.2 is an integer equal to 1 or 2, R.sup.3 represents H or an alkyl group, R.sub.4 represents H, an alkyl group or an aryl group; and R.sup.5 is a divalent radical chosen from the groups of the following formulae: ##STR108##in which:A denotes an aryl group or an alknyl group, R' and R"" denote, independently of each other, H, an alkyl group, aryl, or R' or R"" can be a group ##STR109##where R.sup.a is an alkylene group, and R.sup.b H or CH.sub.3,n takes the values 0 or 1 and 0.ltoreq.m (integer .ltoreq.4), and ##STR110##R.sup.6 denotes H or a methyl group, andCy denotes a substituted or unsubstituted aryl ring.
