Abstract: Ethylene-alkyne copolymers and ethylene-alkyne-alkene terpolymers. The copolymers and terpolymers have a number-average molecular weight, determined by vapor phase osmometry, of from 500 to 500,000 and contain, as copolymerized units, (A) from 70 to 99 percent by weight of ethylene and (B) an acetylenically unsaturated compound of the formula (I) H-C 3BOND C-R1 I where R1 is (OCH2CH2)nH or CH2-R2, n is 1-20, R2 is -OH, -OCOR3 or -COOR3 and R3 is straight-chain or branched C1-C10-alkyl. The terpolymers contain, as copolymerized units, from 50 to 99 percent by weight of (A), from 0.5 to 30 percent by weight of (B) and, in addition, (C) from 0.5 to 49.5 percent by weight of an olefinically unsaturated ester of the formula (II) II where R4 is H or CH3, R5 is -OOC-R6 or -COOR6 and R6 is straight-chain or branched C1-C10-alkyl. The copolymers and terpolymers are prepared in a continuous or batchwise polymerixation system at from 150 DEG to 350 DEG C. under a pressure of from 500 to 3,000 bar in the presence of from 200 to 4,000 mole ppm, based on monomers, of an organic peroxide which decomposes into free radicals. The copolymers and terpolymers can be used as additives to petroleum distillates.
