Title (EN) COPOLYMERS COMPRISING ETHYLENE, VINYL ESTERS AND ESTERS OF (METH)ACRYLIC ACID, THEIR FORMULATIONS AND USE AS POUR POINT DEPRESSANT, WAX INHIBITOR AND FLOW ENHANCER FOR CRUDE OILS
(FR) COPOLYMÈRES COMPRENANT DE L'ÉTHYLÈNE, DES ESTERS DE VINYLE ET DES ESTERS D'ACIDE (MÉTH)ACRYLIQUE, LEURS FORMULATIONS ET LEUR UTILISATION A TITRE D'ABAISSEURS DU POINT D'ÉCOULEMENT, INHIBITEURS DE CIRES ET AMÉLIORATEURS D'ÉCOULEMENT POUR HUILES BRUTES
Abstract:
(EN) Copolymers comprising ethylene, vinyl esters, in particular vinyl acetate and esters of (meth)acrylic acid, selected from esters comprising branched alkyl, cyclic alkyl or optionally alkyl substituted aryl moieties and having a weight average molecular weight of 35,000 g/mol to 150,000 g/mol, formulations of such copolymers in organic solvents and their use as pour point depressant, wax inhibitor and flow enhancer for crude oils.
(FR) Cette invention concerne des copolymères comprenant de l'éthylène, des esters de vinyle, en particulier un acétate de vinyle et des esters d'acide (méth)acrylique, choisis parmi les esters comprenant des fragments alkyle ramifié, alkyle cyclique ou éventuellement aryle substitués par un alkyle et ayant un poids moléculaire moyen en poids de 35 000 à 150 000 g/mol, leurs formulations dans des solvants organiques et leur utilisation à titre d'abaisseurs du point d'écoulement, d'inhibiteurs de cire et d'améliorateurs d'écoulement pour huiles brutes.
