    Abstract: Graft copolymers obtainable by free radical-initiated copolymerization of (A) a monomer mixture comprising (a) a monoethylenically unsaturated C4- to C8-dicarboxylic acid, or an anhydride, alkali metal salt or ammonium salt thereof, (b) a monoethylenically unsaturated C3- to C10-carboxylic acid, or an alkali metal salt or ammonium salt thereof, (c) if desired another monoethylenically unsaturated monomer which can be copolymerized with monomer (a) and (b), and (d) a monomer containing two or more ethylenically unsaturated, non-conjugated double bonds in the molecule, in the presence of (B) a monosaccharide, oligosaccharide, polysaccharide, oxidatively, hydrolytically or enzymatically degraded polysaccharide, oxidized, hydrolytically or enzymatically degraded polysaccharide, or chemically modified monosaccharide, oligosaccharide or polysaccharide, in the weight ratio (A):(B) of (95 to 20):(5 to 80), a process for the preparation of the graft copolymers, and detergents and cleaners containing the graft copolymers in amounts of from 0.1 to 20% by weight, are described.

    Abstract: The novel feature in the prodn. of electroconductive homo- or co-polymers by polymerisation in an electrolyte of 5-membered N-, O- or S-heterocyclics with conj. pi-electron systems or of aniline cpds. is that the polymerisation is effected in the presence of a sulphonic acid-substd. polymeric cpd. The polymsn. is pref. effected by an anodic oxidative process in an electrolyte or is effected with the aid of an oxidn. agent. An (in)org. substrate can be present during the polymsn. The sulphonic acid-substd. polymer is typically of formula (I), where X = -SO3 or its salt; R = H or Me; and Y = -COO- 1-4C alkyl, -CN, -COMe, -COHH, -CONH2, -CONH.CH2OR, Ph or Cl; m = 1-1000; and n = at least 2. USE/ADVANTAGE - The use of the polymers thus obtd. is electrode materials for primary or sec. batteries or as elec. conductors is claimed. The polymers have better electrical conductivity, mechanical properties and electrochemical deposition properties than prior-art polymers, e.g. those of DE3425511 in which a pyrrole- or thiophene-sulphonic acid is used as conductive salt. Typically, the polymers have tear strength above 50 N/mm2 as opposed to only ca. 36 N/mm2 for prior-art polymers. Also depositions of 1 wt.% can be achieved without damage to the polymer.

    Abstract: The use of partially esterified copolymers which can be obtained by copolymerisation of (a) at least one C4- to C28-olefin and (b) ethylenically unsaturated dicarboxylic anhydrides with 4 to 8 C atoms in the molar ratio 1:1 and subsequent partial esterification of the copolymers with reaction products of (A) C1- to C30-alcohols, C8- to C22-fatty acids, C1- to C12-alkylphenols or secondary C2- to C30-amines with (B) at least one C2- to C4-alkylene oxide or tetrahydrofuran in the molar ratio (A):(B) of 1:2 to 50 and hydrolysis of the anhydride groups of the copolymers to carboxyl groups, where the partial esterification of the copolymers is continued until more than 5 to 50% of the carboxyl groups in the copolymers are esterified, as additive to liquid detergent compositions in an amount of 0.1 to 20% by weight and liquid detergent compositions which contain the partially esterified copolymers.
