The invention concerns compounds of formula (1) wherein in particular G represents the -N(CH´3?)´2?-, -N(C´2?H´5?)´2?-group or N-pyrrolidine; n is an integer equal to 1 or 2; R´1?, R´2? and R´3?, independently of one another, represent a hydrogen atom or a methyl group, the successive unsaturated units capable of being moreover identical or different, provided that at least one of the substituents R´1?, R´2? and R´3? is different from H; and Y´1? and Y´2? represent each a -COOCH´3? group or a -COOC´2?H´5? group.
Compos~ de formule (1) dans lesquels notamment G repr~sente le groupe - N(CH~3)~2, -N(C~2H~5)~2 ou N-pyrrolidine, n est un nombre entier ~gal ~ 1 ou 2; R~1, R~2 et R~3 repr~sentent, ind~pendamment l'un de l'autre, un atome d'hydrog~ne ou un groupe m~thyle, les motifs insatur~s successifs pouvant Útre par ailleurs identiques ou diff~rents, ~ condition qu'au moins un des substituants R~1, R~2 et R~3 soit diff~rent de H, et; Y~1 et Y~2 repr~sentent chacun un groupe -COOCH~3 ou un groupe -COOC~2H~5.
