Abstract: This invention describes an ionizing radiation sensitive material having high contrast, high sensitivity and comprised of the mixture of the half-ester or half amide product of reaction of an N-hydroxy or N-aminoalkyl amide with an alkylvinyl ether-maleic anhydride copolymer and the products of reaction of a hydroxy alkyl terminally unsaturated compound with an alkylvinyl ether-maleic anhydride copolymer. A typical material is made by mixing the product of reaction of hydroxyethyl pyrrolidone and octadecylvinyl ether--maleic anhydride copolymer with the products of reaction of the mixture of hydroxyethyl acrylate with octadecylvinyl ether-maleic anhydride copolymer.

Abstract: Double faced rigid polyurethane foam insulating board in which the first facing is adhered directly to the urethane foam and in which a second facing is intermittently adhered to and spaced from the first facing by areas of adhesive spaced so as to allow unrestricted lateral venting of gases from between the facings to the edges of the board.

Abstract: A binder composition for asbestos fibers comprises a latex blend in which the dispersed phase comprises (1) from about 80 to 99.5 weight percent of a synthetic rubber and (2) from about 0.5 to 20 weight percent of a highly carboxylated polymer. The highly carboxylated polymer is a copolymer or terpolymer containing (1) an .alpha.,.beta.-unsaturated carboxylic acid, (2) an alkyl ester of an .alpha.,.beta.-unsaturated carboxylic acid, and optionally (3) an ethylenically unsaturated organic monomer which is copolymerizable with monomers (1) and (2) to form a stable latex.

Abstract: Polymers having a tertiary amide group, particularly homopolymers and copolymers of vinylpyrrolidone, are modified by treatment with reactive acid chlorides, the amide functions being converted into amide chlorides. These modified polymers are reactive intermediates and may be used to obtain a variety of new polymeric substances.

Abstract: Compounds having the formula ##STR1## wherein R represents a C.sub.8 -C.sub.14 aliphatic radical; R.sub.1 represents a C.sub.1 -C.sub.4 lower alkyl radical; R.sub.2 and R.sub.3 each represent H or CH.sub.3 ; M.sub.1 and M.sub.2 represent cations of hydrogen, ammonium, alkyl ammonium, alkali metal, or an equivalent of alkaline earth metal; n is an integer having an average value of from 5 to 10; s and t can either be 0 or 1 but both cannot be simultaneously 0; and A represents an anionic radical such as hydroxide, halogen, sulfate, alkyl sulfate, etc. are useful as essentially non-iritating and high foaming amphoteric surface active agents for shampoo and other cosmetic applications. Preferably R is a naturally derived or synthetic alkyl group containing 10-12 carbon atoms.

Abstract: Complex phosphate ester surfactants derived from a quaternary dihydroxy compound having the formula ##STR1## wherein R and R.sub.1 represent the same or different alkyl moieties containing 1 to 22 carbon atoms, the sum of R and R.sub.1 not being less than 7 carbon atoms; R.sub.2 and R.sub.3 each represent H or CH.sub.3 ; n is an integer having an average value of from 1 to 50; X is an anion of halogen, sulfate, or alkyl sulfate; and wherein the resultant complex phosphate ester contains at least 1/3 P atom per mole of quaternary dihydroxy compound; can be made through reaction of such dihydroxy quaternary compound with a conventional phosphating agent such as P.sub.2 O.sub.5, polyphosphoric acid, or POCl.sub.3 to form interesting amphoteric surface active agents having utility as metal lubricants, heavy duty cleaners, detergents, etc.

Abstract: Polyurethanes incorporating 2,3-dibromobutenediol-1.4, as a reactive fire-retardant component and chain extender, in combination with organophosphorous compounds, to effect a decrease in the amount of brominated diol necessary, and thus in the bromine content of the resin, to provide fire-retardant polyurethane products manifesting significantly reduced smoke emission in the event of combustion and other enhanced physical properties.

Abstract: The mono- or diester of phosphoric acid and a straight chain alkanol of 8 to 10 carbon atoms is used as a surfactant in the emulsion polymerization of olefinic compounds, especially vinyl compounds, to obtain polymers having improved stability to light and heat.
