Abstract: The alkali metal, ammonium and alkanol ammonium salts of polymeric acetal carboxylates are stable detergent builders under laundry use conditions but depolymerize in mildly acidic media, making the polymer fragments more readily biodegradable in waste streams. Such polymeric acetal carboxylates can now be made by a process which comprises bringing together in a reaction zone under polymerization conditions an ester of glyoxylic acid and a polymerization initiator, and adding to the resulting polymer an alkyl vinyl ether and an organoaluminum compound to stabilize the resulting polymer against rapid depolymerization in alkaline solution. The preferred alkyl vinyl ether is ethyl vinyl ether, and the preferred organoaluminum compounds are alkyl aluminum halides and trialkyl aluminum.

Abstract: The alkali metal, ammonium and alkanol ammonium salts of polymeric acetal carboxylates are stable detergent builders under laundry use conditions but depolymerize in acid media, making the polymer fragments more readily biodegradable in waste streams. Such polymeric acetal carboxylates can now be made by a process which comprises bringing together in a reaction zone under polymerization conditions an ester of glyoxylic acid and a molecular sieve, and adding an alkyl vinyl ether to the resulting polymer in the presence of the molecular sieve to stabilize the polymer against rapid depolymerization in alkaline solution. The preferred alkyl vinyl ether is ethyl vinyl ether.

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.

Abstract: The novel condensation product of 1,3-phenylenediamine and glutardialdehyde has high activity to fix or insolubilize proteins, including enzymes.

Abstract: Disclosed is a water-insoluble addition copolymer of an ethylenically unsaturated unsubstituted amide and at least one other ethylenically unsaturated monomer comprising sufficient amide groups mono-functionally bonded to a polyaldehyde to render the copolymer thermosettable. The copolymer is adapted for use as or for formulation in a binder. Such a binder is readily made from a copolymer latex and is useful in processes for the preparation of products such as nonwoven fabrics and bonded papers.

Abstract: The invention is a process for manufacturing low free-formaldehyde crease-proofing compositions for textiles and a process for treating the textile materials therewith.

Abstract: Poly(aldehyde amino silicate) foams are produced by mixing an amino compound, an aldehyde, a silicon oxide compound and a blowing agent; then a curing agent is added, thereby producing a rigid, porous product.

Abstract: Acetylene-substituted tetraimines are synthesized to form oligomers or prepolymers having melting points as low as 40.degree. C. and which can be polymerized into thermoset plastics at temperatures as low as 150.degree. C.

Abstract: Acetylene-substituted Schiff's bases are prepared by the reaction of either acetylene-substituted amines and dicarboxaldehydes or acetylene-substituted aldehydes and diamines.These compounds are polymerizable and in some examples they yield conjugated polymers useful in the fabrication of conductors and semiconductors.

Abstract: New tetracarbonyl compounds of the formulae: ##STR1## where R is a hydrogen atom, an alkyl radical or an aryl radical. The invention also contemplates the thermostable polymers obtained by reacting an aromatic tetra-amine with at least one of the above tetracarbonyl compounds.

Abstract: Benzofuranylphenols are produced by (1) reacting glyoxal with a phenol in the presence of an acidic catalyst to form an acetal, and (2) thereafter partially hydrolyzing the acetal with an acidic or basic catalyst. Some benzofuranylphenols are effective stabilizers of organic materials against the deleterious effects of oxygen, heat and light. The stability of dienic polymers and styrene-acrylonitrile copolymers is particularly enhanced by incorporating stabilizing amounts of some benzofuranylphenols.

Abstract: A process for producing stable urea-aldehyde polymers with high structural strength from two storable liquid ingredients. In this process, partially cured liquid urea-formaldehyde resin is reacted with an aqueous cross-linking solution comprising one or more alkyl or aryl dialdehydes containing two to eight molecular carbons and the hydrogen ion concentration needed to catalyze the completion of the reaction of the dialdehydes and the urea-formaldehyde. The process for producing urea-aldehyde polymers, having improved structural strength and reduced aldehyde vapor emission during their production and prolonged use, is especially effective for manufacturing products for the building industry, such as urea-aldehyde insulating foam, wood-filled particle board, and plywood. The increased polymer strength and the elimination of the hazardous and objectionable aldehyde odor is achieved by maintaining the molecular ratio of total aldehyde moieties to urea to about 1.

Abstract: A novel polyether containing urea-aldehyde resin useful in plastics, sealants, molds, foams and coatings. The novel composition comprises the condensation product of a ureido-terminated polyoxyalkylene and an aldehyde. The ureido terminated polyoxyalkylene compound is prepared by reacting a primary amine terminated polyoxyalkylene with urea at temperatures in the range of about 120.degree. C to about 160.degree. C in a molar ratio of about 1 molecule of urea for each primary amino group.
