Abstract: Partly crosslinked plastic materials with MFI 230/21.6 of 0.1-100 g/10 mins. (I) consist of (a) a polymer and (b) a bis-maleimide cpd. of formula (II). (I) are obtd. by reacting (a) with (b) at 180-280 deg.C and 1-100 bar with mean residence time of 0.2-10 mins. (a) comprises (a1) a polymer of 25-97 wt.% propylene copolymer with 0.1-15 wt.% 2-10C alkene units (A) and 3-75 wt.% other propylene copolymer with 15-80 wt.% 2-10C alkene units (B) or (a2) a polymer of 25-97 wt.% propylene homopolymer (C) and 3-75 wt.% (B) or (a3) a statistical copolymer of propylene with less than 15 wt.% 2-10C alkene units, or (a4) propylene homopolymer with MFI of 0.01-100 g/10 mins. In (II), R is 1-20C alkylene (opt. with in-chain O), 5-7C cycloalkylene or 6-15C arylene (both opt. substd. with 1-10C alkyl, 1-6C alkoxy and/or 1-4C dialkylamino gp(s). or a gp. of formula -R1-Z-R2- (with R1, R2 = 1-10C alkyleme, 5-7C cycloalkylene or 6-10C arylene (opt. substd. as for R), Z = 1-10C alkylene, 1-4C dialkylamino, O or SO2).
