ADDITIVES FOR LOW-SULFOR MINERAL OIL DISTILLATES, COMPRISING GRAFT COPOLYMERS BASED ON ETHYLENE-VINYL ACETATE COPOLYMERS

摘要

The invention provides graft copolymers obtainable by grafting an ester (a) ofaC8- to C22-alcohol and acrylic acid onto a copolymer (b) containing, inaddition toethylene, from 3.5 to 21 mol% of vinyl acetate and from 0.5 to 16 mol% of atleastone vinyl ester of the formula 1CH2=CH-OCOR1 (1)where R1 is C2- to C30-alkyl, with the proviso that the copolymer b) containsless than0.5 mol% of alkenes having 3 to 30 carbon atoms.
