    摘要: 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.tbd.C--R.sup.1 Iwhere R.sup.1 is (OCH.sub.2 CH.sub.2).sub.n H or CH.sub.2 -R.sup.2, n is 1-20, R.sup.2 is -OH, -OCOR.sup.3 or -COOR.sup.3 and R.sup.3 is straight-chain or branched C.sub.1 -C.sub.10 -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) ##STR1## where R.sup.4 is H or CH.sub.3, R.sup.5 is -OOC-R.sup.6 or -COOR.sup.6 and R.sup.6 is straight-chain or branched C.sub.1 -C.sub.10 -alkyl. The copolymers and terpolymers are prepared in a continuous or batchwise polymerixation system at from 150.degree. 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. The copolymers and terpolymers can be used as additives to petroleum distillates.

    摘要: Coating material for a glass mole, especially for a glass gathering mold, consisting of a) a first coating composition, which is to be applied directly on the glass mold and contains a binder on a silicone resin basis, which cures at a temperature elevated above room temperature, for forming a silicone resin carrier layer, a filler, which can be oxidized during the curing and is to be tied into the silicone resins matrix, the binder and the filler being dissolved or suspended in a solvent, and of b) a second coating composition, which is to be applied on the first coating composition and contains a binder on a silicone resin basis, which can be cured at a temperature elevated above room temperature, for forming a silicone resin support layer and a lubricant, which is to be bonded into the silicone resin carrier layer and has a lubricating effect with respect to the glass composition, which comes into contact with this coating layer, the binder and the lubricant being dissolved or suspended in a solvent.
