ABSTRACT:
The invention provides builders for detergent and cleaning compositions. The builders comprise oligomers and/or polymers containing carboxylic and hydroxylic groups -- the latter groups being partially lactonized, if desired -- and a predominant proportion of C--C bonds in their principal chain. The oligomers and/or polymers are produced by hydrolyzing halogenated copolymers which have substantially between 5 and 60 weight % of halogen therein and a principal chain based on structural units, in any desirable sequential arrangement, of the following general formulae I and II or I and III ##EQU1## in which X, Y and Z stand for a hydrogen and/or halogen atom with the proviso that at least one of the X, Y and Z substituents stands for a halogen atom, R stands for a carboxy-halide radical, a carboxylic group, ester group, nitrile group or anhydride group, and the mole fraction m stands for a number greater than zero and smaller than 1.
