Abstract: Compounds of the formula?P!(ACH.sub.2 NH.sub.2).sub.xin which P denotes a partially hydrogenated 1,3-diene oligomer residue, x is practically equal to 2 and A denotes a divalent residue such as ##STR1## are obtained by selective hydrogenation of compounds of formula ?P.sub.1 !(ACN)x in which P.sub.1 denotes a 1,3-diene oligomer residue.

Abstract: Compounds represented by the formulae (I) and (II) in which:R.sup.1 =H or CH.sub.3 ;X=O or S;R.sup.2 =C.sub.1-12 straight-chain or branched alkylene groups, monocyclic or polycyclic cycloalkylene and heterocycloalkylene groups, alkylarylene and arylalkylene groups;R.sup.6 =H or C.sub.1-12 alkyl and aryl radicals;R.sup.3 =C.sub.1-20 alkyl and aryl radicals, --(CH.sub.2).sub.p SR.sup.4 groups where p=integer from 2 to 12 and R.sup.4 =C.sub.1-20 alkyl, and ##STR1## where q is an integer from 2 to 12 and R.sup.5 =H or CH.sub.3.

Abstract: Composite including a rubber/thermoplastic blend adherent by itself to a thermoplastic material; the blend is in the form of a thermoplastic matrix containing rubber nodules functionalized and vulcanized during the mixing with the thermoplastic. Composite articles obtained by overmoulding the vulcanized rubber/thermoplastic blend onto the thermoplastic.

Abstract: These acrylic and methacrylic compounds are chosen from those of the formula: ##STR1## in which R.sup.1 is H or CH.sub.3 ; A is (CH.sub.2).sub.n or n is an integer from 2 to 12 or --(CH.sub.2 CH.sub.2 O).sub.d --CH.sub.2 CH.sub.2 --, d is an integer from 1 to 20; X is S or O; Y is S or O, under the condition that X is S and Y is O when A is --(CH.sub.2 CH.sub.2 O).sub.d --CH.sub.2 CH.sub.2 --; R is C.sub.1 --C.sub.20 alkyl or --(CH.sub.2).sub.p SR.sup.3 where p is an integer from 3 to 12 and R.sup.3 is C.sub.1 -C.sub.20 -alkyl; m is an integer from 1 to 3; and Z is H, R.sup.2 QH, or R.sup.2 is C.sub.2 -C.sub.12 -alkyl and Q is O or S, and the atoms of the metals from Groups IA, IIA, IIIA, IB, IIB, VIB, VIIB and VIII of the Periodic Table, on condition that Z is H or R.sup.2 OH when m is 1 and m is the valence of Z when Z is a metal.
