    Abstract: Plastic materials with a melt flow index 230/2.16 of 0.1-100 g/10 minutes contain: (a1) propylene homopolymer with a melt flow index 230/2.16 of 0.1-100 g/10 minutes, or(a2) statistical copolymer of propylene and 2-10C alkene-1 with a comonomer content of less than 15 wt.%, or (a3) a mixt. of 25-97 wt.% of a copolymer of propylene and 0.1-15 wt.% 2-10C alkene-1 and 3-75 wt.% of another propylene copolymer contg. 15-80 wt.% 2-10C alkene-1 units, or(a4) a mixt. of 25-97 wt.% propylene homopolymer and 3-75 wt.% propylene/2-10C alkene-1 copolymer, with a comonomer content of 15-80 wt.% w.r.t. the second polymer, (b) a propylene or ethylene polymer grafted with 0.1-5 wt.% alpha , beta -unsatd. carboxylic acid or acid deriv., with a melt flow index 230/2.16 of 0.01-400 g/10 minutes, and (c) a nitrogen cpd. of formula (I): R =H, 1-30C alkyl, 2-30C alkyl or alk-1-enyl substd. with O atom(s) and/or amino gps., or a gp. of formula (II):HO-(CHR -CHR )m- (II)R =H, 1-4C alkyl or amino; andm=1-100. Also claimed are: (i) a process for the prodn. of the materials, by reacting components (a)-(c) together at 180-280 deg C and 1-100 bar for a mean residence time of 0.2-10 minutes; and(ii) film, fibres and mouldings made from the materials.

    Abstract: PCT No. PCT/EP93/03573 Sec. 371 Date Jun. 26, 1995 Sec. 102(e) Date Jun. 26, 1995 PCT Filed Dec. 16, 1993 PCT Pub. No. WO94/14873 PCT Pub. Date Jul. 7, 1994There are described water-soluble condensation products of amino-containing compounds and crosslinkers, obtainable by reacting (a) polyalkylenepolyamines, polyamidoamines, ethylene-imine-grafted polyamidoamines, polyetheramines and mixtures thereof, with (b) monethylenically unsaturated carboxylic acids, salts, esters, amides or nitriles of monoethylenically unsaturated carboxylic acids, chlorocarboxylic acids and/or glycidyl compounds such as glycidic acid, glycidamide or glycidyl esters, and (c) at least bifunctional crosslinkers having a halo-hydrin, glycidyl, aziridine or isocyanate unit or a halogen atom as functional group, to form water-soluble condensation products having a viscosity of at least 100 mPas in a 20% strength by weight aqueous solution at 20 DEG C., processes for preparing the water-soluble condensation products by reacting the abovementioned compounds of groups (a), (b) and (c), and the use of the condensation products as drainage, flocculation and retention aids in papermaking.
