Abstract: Solid golf balls, characterized by high initial velocity as well as outstanding retention of properties on continued hitting, are made from a blend of a resilient elastomer (e.g., cis-polybutadiene) and zinc oxide-methacrylic acid reaction product, the composition being cured with a free-radical cross-linking agent such as peroxide.

Abstract: Potassium salt of 2-pyrrolidinone is used as a catalyst to cyclotrimerize an organic diisocyanate, yielding a mixture of monomeric cyclotrimerized product (isocyanurate) and oligomers thereof, soluble in common organic solvents and vinyl monomers. The catalyst can be used to make one-shot isocyanurate-crosslinked polyurethanes. Prepolymers and moisture-curing coating compositions can also be prepared.

Abstract: 2,3-Dihydro-5,6-diphenyl-1,4-oxathiin is prepared by reacting benzoin and 2-mercaptoethanol in an alkanol solvent of 2 to 8 carbon atoms and an acidic catalyst. The use of alcohol solvent in lieu of aromatic solvents gives much greater purity with much better yields.

Abstract: This method of making 5,6-dihydro-2-methyl-N-phenyl-1,4-oxathiin-3-carboxamide is based on the use of an oxathiolane, namely, 2-methyl-N-phenyl-1,3-oxathiolane-2-acetamide, which may be formed by condensing 2-mercaptoethanol with acetoacetanilide under acidic conditions in a solvent medium (aromatic hydrocarbon, chlorinated hydrocarbon or alkyl ester of an aliphatic acid). The said oxathiolane, with or without purification, is reacted with hydrogen peroxide in water or in a water-organic solvent mixture under basic conditions in the presence of a catalytic amount of a metal compound such as sodium tungstate to form 2-methyl-N-phenyl-1,3-oxathiolane-2-acetamide 3-oxide.

Abstract: Long chain aliphatic alcohol (C.sub.16 +) is added to thermoplastic elastomer based on blend of olefin copolymer rubber (EPM or EPDM) and polyolefin resin (especially polypropylene). The blend may be uncured or dynamically partially cured. The long chain aliphatic alcohol permits injection molded articles to be demolded within a shorter time without tearing or distortion, and decreases the surface tackiness of the article.

Abstract: A chlorinated polyethylene elastomer or resin is modified by graft copolymerization with acrylic ester type of monomeric material, whose homopolymers have a glass transition temperature of not greater than 6.degree. C., in an amount sufficient to provide an ester group (--COO--) content of from 25 to 40% by weight, to yield a mixed copolymerizate vulcanizable to a heat and oil resistant elastomeric state.

Abstract: Energy absorbing polyurethane foam is made by reaction of an aromatic polyisocyanate with a polyether triol having dissolved therein a monofunctional bulky modifying ingredient, such as 2-naphthol.

Abstract: New chemicals containing two diphenylaminomethane groups, linked together by a moiety other than oxygen, e.g., 1,2-bis[4-(3-methyl-alpha-amino-benzyl)phenoxy]ethane, are effective antimicrobial agents useful as agricultural or industrial fungicides and bactericides.

Abstract: A thermoplastic composition characterized by high impact strength and flex-resistance, based on a graft copolymer of resin-forming monomer (e.g., styrene-acrylonitrile) on EPDM type of rubber (especially a terpolymer of ethylene, propylene and 5-ethylidene-2-norbornene) having a Mooney viscosity of at least 55 ML-4 at 257.degree.

Abstract: The use of di- and triaryl-substituted thiazoles as pesticides is disclosed. Insects, such as mosquitos, and acarids, such as mites and ticks, are among the pests which may be controlled.

Abstract: Thermoplastic blends of partially cured monoolefin copolymer rubber (such as EPM or EPDM rubber) with a polyolefin resin (such as polypropylene) exhibit good physical properties and are reprocessable. The partial cure of the rubber is effected by heating the rubber with a curative such as a peroxide. The blends are used to make molded or extruded articles which have good physical properties without requiring vulcanization; preferred blends have the characteristics of thermoplastic elastomers.
