| titleOfInvention | Copolymers of ethylene and alkynes; manufacture and use thereof as additives in petroleum distillates |
| abstract | (A) mindestens 70 und maximal 99 Gewichtsprozent Ethylen und (B) eine acetylenisch ungesättigte Verbindung der allgemeinen Formel (I)n wobei R. 1 = (OCH 2 CH 2 ) n H oder CH 2 -R 2 und n = 1 bis 20 und R 2 = -OH, -OCOR 3 oder -COOR 3 bedeuten und R 3 eine geradkettige oder verzweigte C 1 - bis C 10 -Alkylgruppe ist. nGeeignet sind insbesondere ternöre Ethylen-Alken-Copolymerisate, bestehend aus 50 bis 99 Gewichtsprozent einpolymerisierter Einheiten (A) und 0,5 bis 30 Gewichtsprozent einpolymerisierter Einheiten (B) sowie zusätzlich (C) 0,5 bis 49,5 Gewichtsprozent eines olefinisch ungesättigten Esters der allgemeinen Formel (II)n wobei R 4 = H oder CH 3 und R 5 = -OOC-R 6 oder -COOR 6 und R 6 eine geradkettige oder verzweigte C 1 - bis C 10 -Alkyl-Alkylgruppe aus (A), (B) und (C) 100 ist. The invention relates to ethylene-alkyne copolymers with an average number-average molecular weight, determined using a vapor phase osmometer, between 500 and 500,000, preferably between 500 and 10,000, in particular between 1,000 and 5,000, which contain in copolymerized form (A) at least 70 and at most 99 weight percent ethylene and (B) an acetylenically unsaturated compound of the general formula (I) where R. 1 = (OCH 2 CH 2 ) n H or CH 2 -R 2 and n = 1 to 20 and R 2 = -OH, -OCOR 3 or -COOR 3 and R 3 is a straight-chain or branched C 1 - to C 10 alkyl group. Particularly suitable are ternary ethylene-alkene copolymers consisting of 50 to 99 percent by weight of polymerized units (A) and 0.5 to 30 percent by weight of polymerized units (B) and additionally (C) 0.5 to 49.5 percent by weight of an olefinically unsaturated ester of the general formula (II) where R 4 = H or CH 3 and R 5 = -OOC-R 6 or -COOR 6 and R 6 is a straight-chain or branched C 1 - to C 10 -alkyl alkyl group from (A), (B) and (C) 100 is. n n n The invention also relates to a process for the preparation of the ethylene-alkyne copolymers, the copolymerization of ethylene with an acetylenically unsaturated compound of the general formula I and optionally with an olefinically unsaturated ester of the general formula II in a continuously or batchwise operated polymerization system at temperatures of 150 to 350 ° C and at pressures of 500 to 3000 bar in the presence of a free radical organic peroxide, optionally oxygen and optionally a polymerization is carried out, polymerizing in the presence of 200 to 4000 molppm peroxide, based on the monomers.n n n The ethylene-alkyne copolymers can be used as an additive to petroleum distillates in amounts of 0.001 to 2.0 percent by weight. |
