ABSTRACT:
Copolymers of keto dicarboxylates are provided which have the following general formula ##STR1## WHERE Y is one or more comonomers; n averages at least 2; p is at least 1; and M is selected from the group consisting of alkali metal, ammonium, alkyl groups having 1 to about 4 carbon atoms, and alkanol amine groups having 1 to about 4 carbon atoms in the alkyl chain. Such copolymers are useful as detergent builders to replace sodium tripolyphosphate (STP) in detergent formulations. The copolymers are stable under laundry use conditions, but depolymerize in acid media, making the fragments more readily biodegradable in waste streams.
