ABSTRACT:
Oligomers of the formula ##STR1## wherein: (1) at least one A=--CH.sub.2 CHR.sup.1 COODOH (a) (R.sup.1 =H, CH.sub.3 and D=C.sub.1 -C.sub.4 alkylene), the other A's=H or C.sub.1 -C.sub.4 alkyl, it being possible for at least a part of the residues (a) to be converted into A.sup.1 =--CH.sub.2 CHR.sup.1 COODOCONHD.sup.1 NCO (D.sup.1 =divalent organic residue), it being possible for at least a part of the residues A.sup.1 to be converted into A.sup.2 =--CH.sub.2 CHR.sup.1 COODOCONHD.sup.1 NHCOOR.sup.2 (R.sup.2 =monovalent radical obtained by removal of OH from a monoalcohol containing a vinylidene group);
