  • Patent number: 4201858
    Abstract: Ether and acetal carboxylates useful as detergent builders to replace sodium tripolyphosphate (STP) in detergent formulations are known to the art. Certain polymeric polycarboxylates are also known to the art but all of these products suffer from either having poor builder properties or they are not readily biodegradable. According to the present invention, a method is provided for preparing new and novel 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.

  • Patent number: 4189416
    Abstract: Disclosed herein is a composition and method for sizing textiles which employs as the sizing agent a mixed salt comprising the reaction product of an interpolymer with a fixed alkali base and a fugitive alkali base; the latter subsequently being volatilized away during processing of the sized textile. The interpolymer comprises (a) 1.0 molar proportion of a maleic or fumaric acid or anhydride or partial ester, (b) from 0.1 to 3.0 molar proportion of a monovinylidene aromatic monomer and (c) from zero to a finite molar proportion of an alpha-olefin, a vinyl ester alpha-beta-ethylenically unsaturated nitrile, an acrylic or methacrylic ester or a vinyl alkyl ether. From 10 to 70% of the free carboxyl groups of the interpolymer are combined with fixed base, i.e., non-volatile amine or alkali metal base, and from 5 to 90% of said free carboxyl groups are combined with fugitive base, i.e., ammonia, ammonium hydroxide or volatile amine.
