Abstract

STABILISATION DE LA VISCOSITE D'HOMOPOLYMERES DU CHLOROPRENE OU DE COPOLYMERES DE CELUI-CI AVEC DES MONOMERES ETHYLENIQUES OU AVEC DU SOUFRE, OU ENCORE DE MELANGES DE CES MATIERES POLYMERES AVEC DES ELASTOMERES DE DIENES. ON AJOUTE COMME STABILISANT A CES MATIERES POLYMERES 0,1 A 5 EN POIDS D'UN ESTER, D'UN AMIDE OU D'UN ACIDE AMIQUE (CARBOXYAMIDE) DERIVANT DE L'ACIDE MALEIQUE OU FUMARIQUE OU D'UN COMPOSE DIACYL-ETHYLENIQUE OU DE LEURS DERIVES HALOGENES. CE TRAITEMENT DE POLYMERES DU CHLOROPRENE FORMES SANS SOUFRE ELEMENTAIRE PERMET DE LES MELANGER AVEC LES INGREDIENTS HABITUELS A DES TEMPERATURES ELEVEES ET AVEC UNE FORTE ACTION DE CISAILLEMENT SANS QU'ILS SUBISSENT UNE RETICULATION NOTABLE PENDANT LE TEMPS NECESSAIRE AU TRAITEMENT, TANDIS QUE LES POLYMERES DE CHLOROPRENE MODIFIES AU SOUFRE SONT PROTEGES CONTRE UNE ELEVATION DE LEUR VISCOSITE AU COURS D'UN VIEILLISSEMENT A LA TEMPERATURE AMBIANTE.
