Abstract
The invention concerns new polyfunctional ethylenic monomers of the general formula (I): ##STR1## where R.sub.1 and R.sub.2 each represent --CHR.sub.3 R.sub.4 where R.sub.3 and R.sub.4 may be identical or different and represent H or an alkyl, alkenyl or aralkyl group. R.sub.1 and R.sub.2 may, alternatively, together form a radical --CH.sub.2 --(CR.sub.5 R.sub.6).sub.n --CHR.sub.7 where n=0 or 1 and R.sub.5, R.sub.6 and R.sub.7 may be identical or different and represent H or CH.sub.3. Particular monomers are: PA1 2-cyano-4,4-dimethoxy-3-hydroxy-1-butene; PA1 2-cyano-4,4-dibutoxy-3-hydroxy-1-butene.
