    摘要: The invention concerns new polyfunctional ethylenic monomers of the general formula (I): ##STR1## where R=cyano, substituted or unsubstituted acyl, substituted or unsubstituted alkoxycarbonyl or substituted or unsubstituted aryloxycarbonyl; 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: 2-cyano-4,4-dimethoxy-3-hydroxy-1-butene; 2-cyano-4,4-dibutoxy-3-hydroxy-1-butene; 4,4-dibutoxy-2-ethoxycarbonyl-3-hydroxy-1-butene; 2-butoxycarbonyl-4,4-dibutoxy-3-hydroxy-1-butene; 4,4-dimethoxy-2-hydroxythoxycarbonyl-1-butene; 4,4-dimethoxy-2-dimethylaminoethoxycarbonyl -3-hydroxy-1-butene; and 4,4-dimethoxy-2-ethoxycarbonyl-3-hydroxy-1-butene.

    摘要: They have the formula: ##STR1## where either R.sub.1 and R.sub.2 are identical and represent --CH.sub.2 R where R=H or a C.sub.1 to C.sub.4 alkyl group or R.sub.1 and R.sub.2 together form the --CH.sub.2 (CR.sub.4 R.sub.4).sub.n --CH.sub.2 group where n=0 or 1, R.sub.4 =H or --CH.sub.3, R.sub.3 =H or --CH.sub.2 R.sub.5 where R.sub.5 =H or a C.sub.1 to C.sub.4 alkyl group. A and A.sub.1 are either identical and represent H or A and A.sub.1 together form an ethylene, trimethylene or --CH(OCH.sub.2 R.sub.6)--CH(OCH.sub.2 R.sub.6)-- radical where R.sub.6 =H or a C.sub.1 to C.sub.4 alkyl group or, when R.sub.3 =H, a 1,2 dihydroxy-ethylene group.They are obtained by reacting a disubstituted ethanal ##STR2## with a urea ANH--CO--NHA, followed if required by etherification with an alcohol R.sub.5 CH.sub.2 OH.
