ADDITIVES FOR LOW-SULFUR MINERAL OIL DISTILLATES, COMPRISINGGRAFT COPOLYMERS BASED ON ETHYLENE-VINYL ESTER COPOLYMERS

摘要

The invention provides graft copolymers obtainable by grafting an ester (a) of a C8- to C22-alcohol and acrylic acid onto a copolymer (b) containing, in addition to ethylene, from 0.5 to 16 mol% of at least one vinyl ester of the formula 1 CH2=CH-OCOR1 (1) where R1 is a branched C5- to C15- alkyl radical, with the proviso that the copolymer b) contains less than 3.5 mol% of vinyl acetate.
