Abstract: A process for the preparation of polymaleic acid by polymerizing maleic anhydride in an aromatic hydrocarbon at from 60 DEG to 200 DEG C., using from 1 to 20% by weight, based on maleic anhydride, of peroxyesters derived from saturated or ethylenically unsaturated carboxylic acids, as the polymerization initiators and hydrolyzing the polymer, the polymaleic acid thus obtained and the use of the polymaleic acid as an agent for reducing scale formation and hard water deposits in systems through which water flows.

Abstract: The invention concerns polycocondensates of aspartic acid, obtained by condensing aspartic acid in the presence of carboxylic-group-containing polymers which include at least 10 mol % of a monoethylenically unsaturated carboxylic acid polymerized into the polymer and have a molecular weight of at least 300, in the ratio by weight of 1000:1 to 2:1. The invention also concerns methods of producing such polycocondensates and the use of the polycocondensates, in a form with free acid groups or in a form with the acid groups neutralized with ammonia, amines, alkali-metal bases or alkaline-earth bases, as an additive in washing and cleaning agents, as scale inhibitors or as dispersants for finely divided solids.

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.
