Abstract: Copolymers of acetal carboxylates are provided which have the following empirical formula ##STR1## where Y is one or more comonomers randomly distributed in the copolymer; the product of n and q averages at least 4; 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 ammonium 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.

Abstract: The mold deposit problem commonly associated with polyoxymethylene molding compositions which creates a non-uniform surface on a molded article effectively is minimized. The polyoxymethylene polymer initially is heated (as described) while in admixture with about 1 to about 4 percent by weight based upon the weight of the oxymethylene polymer of an aromatic polycarbonate (as defined). In a preferred embodiment a minor quantity of malonamide also is admixed with polyoxymethylene polymer and the aromatic polycarbonate during heating.
