Polymeric acetal carboxylates, a method for their preparation and their use in a detergent composition.

摘要

The polymerization of an ester of glyoxylic acid aldehyde followed by end group stabilization gives polymeric acetal carboxylates which are stable under laundry use conditions, but depolymerize in acid media, making the polymer fragments more readily biodegradable in waste streams. The polymeric acetal carboxylates have the empirical formula <CHEM> they are useful as detergent builders to replace sodium tripolyphosphate (STP) in detergent formulations.
