Abstract

Procédé pour la synthèse de copolymères en bloc du type ABC, dans lesquels : A est une séquence homopolymère d'un monomère vinylique tel que, par exemple, le styrène, l' -méthylstyrène, le vinyldiphényle, l'isopropényldiphényle, le vinylnaphtalène, l'isopropénylnaphtalène; B est une séquence homopolymère d'un monomère diénique ou d'un de ses produits hydrogénés, et C est une séquence homopolymère de pivalolactone (PVL). Le procédé est constitué par trois étapes : 1) polymérisation de la séquence vinlique ; 2) addition de la séquence diénique sur la séquence vinylique, au moyen de la polymérisation ultérieure du diène; 3) carboxylation de la section AB, traitement avec un sel téraalkylammonium et polymérisation de la pivalolactone. Ces copolymères en bloc présentent les propriétés typiques des produits thermoélastomères.Process for the synthesis of block copolymers of the ABC type, in which: A is a homopolymer block of a vinyl monomer such as, for example, styrene, 1-methylstyrene, vinyldiphenyl, isopropenyldiphenyl, vinylnaphthalene, l isopropenylnaphthalene; B is a homopolymer block of a diene monomer or one of its hydrogenated products, and C is a homopolymer block of pivalolactone (PVL). The process consists of three stages: 1) polymerization of the vinic sequence; 2) addition of the diene block to the vinyl block, by means of the subsequent polymerization of the diene; 3) AB section carboxylation, treatment with a teraalkylammonium salt and polymerization of pivalolactone. These block copolymers have the properties typical of thermoelastomeric products.
