    摘要: Low viscosity mixtures of(I) from 40 to 97.5% by weight of amphiphilic nonionic graft copolymers comprising, in copolymerized form,(a) at least 20% by weight of polyalkylene oxide units or polyvinylpyrrolidone units as hydrophilic part of the molecule and(b) at least 40% by weight of vinyl ester and/or (meth)acrylic ester units as hydrophobic part of the molecule, and(II) from 2.5 to 60% by weight of at least one viscosity-reducing additive selected from the group consisting of polyalkylene glycols, alkoxylated alcohols, alkoxylated alkylphenols, alkoxylated amines and hydroxy compounds having from 1 to 4 OH groups and from 2 to 10 carbon atoms, the molecular mass M.sub.N of the polymers in each case being not more than 2500, and(III) from 0 to 40% by weight of homogenizing or phase-stabilizing additives, for example water, monobasic and dibasic carboxylic acids having from 8 to 25 carbon atoms, fatty alcohol sulfates and fatty alcohol sulfonates or mixtures thereof,are useful as detergent and cleaner additives.

Fikentscher on the sodium salt in 1% strength by weight aqueous solution at 25.degree. C. and pH 7) of at least 8.5, and are prepared by polymerizing compounds of the formula ##STR2## where R is hydrogen, C.sub.1 -C.sub.4 -alkyl or COOM,M is C.sub.1 -C.sub.4 -alkyl or an alkali metal, ammonium or alkanolamine group,R.sup.2 is C.sub.1 -C.sub.4 -alkyl, andm is from 0 to 9,in the presence of initiators and optionally comonomers with or without hydrolysis of the ester groups.
