Abstract
Novel block copolymers comprising from 20 to 95 mole % of monomer units derived from itaconic acid or a homologue thereof and from 5 to 80 mole % of monomer units derived from vinyl alcohol or a lower vinyl ester are excellent binders of divalent or polyvalent metals and are useful as potentially biodegradable builders in detergent compositions as well as in machine dishwashing compositions and anti-scaling rinse compositions.
