    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.

    Abstract: Ethylene-alkyne copolymers which have a number-average molecular weight, determined by vapor phase osmometry, of from 500 to 500,000, preferably from 500 to 10,000, especially from 1,000 to 5,000, and which contain, as copolymerized units, (A) from 70 to 99 percent by weight of ethylene and (B) an acetylenically unsaturated compound of the general formula (I) H-C?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 . Particularly suitable copolymers are ternary ethylenealkyne-alkene copolymers which 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 general 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 or hydrogen, and the sum of the percentages by weight of (A), (B) and (C) is 100, and a process for the preparation of the ethylenealkyne copolymers, wherein the copolymerization of ethylene with an acetylenically unsaturated compound of the general formula I, with or without an olefinically unsaturated ester of the general formula II, is carried out in a continuous or batchwise polymerization system at from 150 to 350.degree.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, in the presence or absence of oxygen and in the presence or absence of a polymerization regulator. The ethylene-alkyne copolymers can be used, in amounts of from 0.001 to 2.0 percent by weight, as additives to petroleum distillates.
