    Abstract: Partly crosslinked polyolefin mixt. consists of: (a) a polymer of 25-97 wt.% propylene polymer (IA) contg. 0-15 wt.% copolymerised 2-10C alk-l-ene cpds. (II) and 3-75 wt.% propylene polymer (IB) contg. 15-80 wt.% copolymerised (III); (b) a random ethylene copolymer with 5-20 wt.% copolymerised 3-10C alk-l-ene cpds. and a density of 0.890-0.930 g/cc at room temp.; (c) a homogeneous mixt. of a high mol. polyisobutylene (IV) with an Mn of at least 80,000 and a polyolefin; and (d) a bis-maleimido cpd. of formula (V). In (V): R = 1-20C alkyl, opt. with ether O atom(s) in the chain, 5-7C cycloalkyl or 6-15C aryl, opt. with 1-10C alkyl, 1-6C alkoxy and/or 1-4C dialkylamino substit(s).; or an R -Z-R gp.; R , R = 1-10C alkyl, 5-7C cycloalkyl or 6-10C aryl, opt. with 1-10C alkyl, 1-6C alkoxy and/or 1-4C dialkylamino substit(s).; Z = 1-10C alkyl, 1-4C dialkylamino, -O- or -SO2-. Also claimed are: (i) a method for producing the mixt.; and (ii) films, fibres, mouldings and foam made from the mixt.

    Abstract: The invention relates to a polypropylene-based bumper system comprising a bumper support A (1) comprising glass fibre-reinforced polypropylene, an energy-absorbing foam core B (2) comprising foamed polypropylene, and a tough shell C (3) which comprises EP rubber-modified polypropylene and may, if desired, be painted. The bumper system can be recycled by mechanical comminution, extrusion and granulation. The granules can be used to produce injection mouldings having good mechanical properties.

    Abstract: Thermoplastics moulding compsn. contains (w.r.t. A+B) (A) 5-95 (wt.)% resin(s) consisting of (a1) 8-12C vinylaromatic monomer(s), (a2) alpha,beta-unsatd. dicarbonyl monomer(s) and (a3) elastomer(s) (rubber) and (B) 95-5% polyamide(s). The novelty is that resin (A) is obtd. by grafting (a1) to an unmodified resin in the presence of a3, then modification in the melt at 120-280 deg.C in the presence of a2, using the monomers in such amts. that A consists of 97-50% a1, 0.05-10% a2 and 3-50% a3.
