Abstract: Polyester-imide resins are prepared which are soluble in non-phenolic solvents by incorporating a monoether of a diethylene glycol or triethylene glycol into the resin.

Abstract: Water soluble polyesters are prepared by reacting an aromatic dicarboxylic acid, a diol and a triol (the molar ratio of diol to triol being 75:25 to 40:60) with or without a monohydric alcohol. The polyesters have a molecular weight of 800 to 1300, an OH/COOH ratio of 1.8:1 to 3:1. The polyesters are useful in making wire enamels.

Abstract: An acrylonitrile-butadiene-styrene terpolymer is added to a phenol formaldehyde novolak to produce a mixture which materially increases the resistance to peelback as compared to the phenol formaldehyde novolak alone when used as a shell process foundry resin.

Abstract: An acrylonitrile-butadiene-styrene terpolymer is added to a phenol formaldehyde novolak to form a grinding wheel binder imparting increased flexural strength to the grinding wheel.

Abstract: A tackifier system which includes the reaction product of oxirane bearing materials with alkyl phenol novolacs for elastomers of alpha-olefin polymers which are sulfur curable.The invention is directed to reaction products of alkyl phenol novolacs with oxirane bearing materials. The reaction products of alkyl phenol novolacs with oxirane bearing materials have been found to be excellent tackifiers for various types of elastomers.Further, the invention is directed to elastomer compositions containing reaction products of alkyl phenol novolacs with oxirane bearing materials. Elastomer compositions containing the reaction products of alkyl phenol novolac resins with oxirane bearing materials exhibit excellent tack properties.Tackifiers are employed in elastomeric compositions to produce wider practical ranges of elastomer properties, such as stiffness and tack. Tackifiers are used to improve adhesion, and sometimes cohesion without necessarily stiffening or softening the elastomer composition.

Abstract: A composition is prepared which is useful in wire enamel, comprising (1) a water soluble polyester which is a condensation product of (a) a tribasic carboxylic acid, (b) an aliphatic or aromatic dicarboxylic acid and (c) a dihydric alcohol, (2) hydroxylmethylated diacetone acrylamide as a crosslinking agent and a water soluble organic titanate.This application is a division of application Ser. No. 536,963, filed Dec. 27, 1974, now U.S. Pat. No. 3,974,115, which in turn is a continuation-in-part of application Ser. No. 311,701 filed Dec. 7, 1972.

Abstract: Superior polychloroprene adehsives are prepared by incorporating the reaction product of an alkali catalyzed alkyl phenol-formaldehyde resin and zinc resinate. Preferably an arylphenol and/or bisphenol A is also incorporated. Also preferably rosin is included in the composition. Other zinc compounds, e.g. zinc oxide, zinc borate, zinc phosphate, zinc carbonate, and zinc salicylate can be used in place of zinc resinate.

Abstract: Amide-imide-hydantoin polymers are prepared from trimellitic anhydride, a diisocyanate and reacting the isocyanate terminated amide-imide with a glycine derivative of the formula ##STR1## WHERE R is aromatic, R.sub.1 are the same or different and are hydrogen or alkyl, R.sub.2 is dialkylamino, alkoxy or aroxy and x is an integer from 2 to 4. A portion of the trimellitic anhydride can be replaced by a dicarboxylic acid, a dianhydride or a tribasic acid. The products are soluble in cresol type solvent.

Abstract: Styrene is homopolymerized or copolymerized with alpha methyl styrene, preferably in the presence of limonene, with or without t-butyl styrene, using zirconium tetrachloride as the catalyst. The light colored resins formed are useful as .[.drying.]. .Iadd.dry .Iaddend.cleaning sizing agents and in hot melt adhesives.
