    Abstract: The use of copolymers which contain as essential copolymerised units (a) 50 to 99 mol% of units of monoethylenically unsaturated (a) C3- to C8-monocarboxylic acids, monoethylenically unsaturated C4- to C8-dicarboxylic acids, hemiesters of monoethylenically unsaturated C4- to C8-dicarboxylic acids, esters of monoethylenically unsaturated C3- to C8-carboxylic acids, C2- to C30-olefins, styrene, C1- to C3-alkylstyrenes, C1- to C28-alkyl vinyl ethers, vinyl esters of saturated C1- to C8- carboxylic acids or mixtures of units of these monomers and (b) 50 to 1 mol% of units of amides of monoethylenically unsaturated C3- to C8-carboxylic acids with amide groups of the structure … … in which R = C8- to C28- alkyl, … … R , R = H, CH3, C2H5 R = C1- to C28-alkyl, n = 2 to 100 and R = H, R have K values of 8 to 200, or of salts of these copolymers, as additive to liquid detergent compositions in an amount of 0.1 to 20% by weight and aqueous liquid detergent compositions which contain these copolymers.

    Abstract: Described are maleic acid imide alpha -olefin copolymers with a mean molecular weight of 1,000 to 50,000, built up of structural units of the formula I, R being a tetramethylpiperidinyl grouping of the formula II in which R is hydrogen, C1 to C6 alkyl, formyl, C2 to C6 alkanoyl, C1 to C12 alkoxy, C5 to C6 cycloalkoxy, cyanomethyl, 2-Hydroxyethyl, benzyl or a group of the formula -CR = CH-CO-OR , R being hydrogen,C1 to C6 alkyl or a group of the formula -CO-OR , and r being C1 to C18 alkyl, C5 to C8 cycloalkyl, C7 to C18 aralkyl, phenyl or tolyl, where R can also denote, in a quantity of up to 8 mole % relative to II, hydrogen, C1 to C22 alkyl or C5 to C8 cycloalkyl, and R is a mixture of C14 to C28 alkyl groups, two of these alkyl groups, which may not differ from each other by more than two C-atoms, constituting at least 30 % of this mixture. The copolymers described are suitable for use as light-protection agents and stabilizers for organic materials, particularlyplastics and paints.

    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.
