    Abstract: Propylene polymers (I), containing (a) 50-95 pts. wt.propylene homopolymer with an MFI 230/2.16 (ISO 1133) of 0.1-100 g/10 mins. and an isotacticity of at least 98%, (b) 5-50 pts. wt. ethylene copolymer with a density of 0.865-0.920 g/cm containing 4-40 wt% 4-20C alkene-1 units, and (c) 0-1.5 pts. wt. nucleating agent, in which the total amount of (a) + (b) = 100 pts. wt. Also claimed is a process for the production of (I) by compounding the components at 200-250 degrees C in a mixing apparatus, preferably an extruder.

    Abstract: A process for the preparation of multiphase homopolymers or copolymers of C2-C10-alk-1-enes, characterised in that the polymerisation is carried out in one reaction zone in the presence of two different catalyst systems, where one of the catalyst systems contains, as active constituents, a metallocene complex of the formula (I) or (II) in which M is a metal from group IVb, Vb or VIb of the Periodic Table, R and R are identical or different and are a hydrogen atom, a C1-C10-alkyl group, a C1-C10-alkoxy group, a C6-C10-aryl group, a C6-C10-aryloxy group, a C2-C10-alkenyl group, a C7-C40-arylalkyl group, a C7-C40-alkylaryl group, a C8-C40 arylalkenyl group or a halogen atom, R and R are identical or different and are a hydrogen atom, a halogen atom, a C1-C10-alkyl group, which may be halogenated, a C6-C10-aryl group, an -NR 2, -SR , -OSiR 3, - SiR 3 or -PR 2 radical, in which R is a halogen atom, a C1-C10-alkyl group or a C6-C10-aryl group, and R and R are identical or different and are as defined for R and R with the proviso that R and R are not hydrogen.

    Abstract: Partly crosslinked plastic materials (A) with a melt flow index 230/2.16 of 0.1-100 g/10 minutes are obtd from: (a1) a polymer contg: (a1.1) 25-97 wt% of a copolymer of propylene with 0.1-15 wt% 2-10C alkene-1, and (a1.2) 3-75 wt% of a copolymer of propylene with 15-80 wt% 2-10C alkene-1; or (a2) a polymer contg: (a2.1) 25-97 wt% propylene homopolymer, and (a2.2) 3-75 wt% copolymer (a1.2) as above; or (a3) a propylene homopolymer with a melt flow index 230/2 of 0.1-100 g/10 minutes; or (a4) a statistical propylene copolymer contg less than 15 wt% 2-10C alkene-1 comonomer; and (b) a cpd of formula: (H2C=CR-COO)nX (I) R = H or 1-4C alkyl; X = 1-30C alkyl or 7-30C aralkyl, opt contg in-chain O and/or N atom(s); and n = 2 or 3; and these materials (A) are obtd by reacting (a1), (a2), (a3) or (a4) with cpd (b) at 180-280 deg C and 1-100 bar for a mean residence time of 0.2-10 minutes. Also claimed are: (i) a process for the prodn of (A) by reacting the above polymers with (b) at 190-260 deg C and 1-60 bar for a mean residence time of 0.2-5 minutes, pref immediately after prodn of the polymer in a mixer connected to the polymerisation reactor; and (ii) films, fibres and mouldings made from (A).
