    Abstract: Propylene copolymers which contain up to 35% by weight of other C2- to C10-alk-1-enes and are grafted with alpha , beta -ethylenically unsaturated carboxylic acids or carboxylic acid derivatives can be obtained by reacting the monomer to be grafted with a propylene copolymer at a pressure of from 1 to 500 bar, where from 0.01 to 1.0% by weight, based on the propylene copolymer, of the monomer to be grafted is added to the molten propylene copolymer in the absence of an initiator which decomposes to form free radicals, and the grafting reaction is carried out at a temperature of from 210 to 350 DEG C. The propylene copolymers according to the invention can be converted into crosslinked or crosslinkable propylene copolymers by admixing with organic crosslinking agents.

    Abstract: The invention relates to a process for the preparation of ionically crosslinked ethylene copolymers by mixing the carboxyl group-containing copolymers with an aqueous metal salt solution in the reaction zone of a twin-screw extruder and transferring the reaction mixture into a degassing zone, to an ionically crosslinked ethylene copolymer, and to its use as a coupling agent, injection-moulded article or coating film.

    Abstract: Ionically crosslinked ethylene coolymers prepared by neutralizing the corresponding ethylene copolymers with the addition of an ionomer to a feed zone of an extruder of an ethylene high pressure polymerization system are used for film production, for cable sheathing and as adhesion promoters.

    Abstract: Copolymers (I) of propylene (P) and up to 35 wt.% other 2-10C 1-alkenes (II), grafted with alpha,beta-unsatd. carboxylic acids or derivs. (III) are claimed. (I) are obtd. by reaction of (III) with the (P) copolymer at 1-500 bar in the absence of radical initiators, by adding 0.01-1 wt.% (III) to the molten copolymer and carrying out the grafting reaction at 210-350 deg.C. Also claimed are (a) crosslinked copolymers obtd. by reaction of (I) with organic crosslinkers (IV) at 1-500 bar and 21-0350 deg. 210-350 deg.C. (b) the crosslinking process, (c) crosslinkable copolymers obtd. by mixing (IV) with (I) for less than 30 secs. at 1-500 bar and below 210 deg.C and rapidly cooling the mixt. and (d) ionomers obtd. by reacEP467178A - A3tion of (I) with salts of (in)organic acids and alkali, alkaline earth or transition metals. The copolymer specifically consists of 40-95 wt.% homo-polypropylene and 5-60 wt.% statistical copolymer of (P) and (II), or a statistical copolymer contg. up to 20 wt.% (II); process (e) is carried out at not above 200 deg.C for not above 25 secs.
