Abstract: A resinous material, suitable for use in hot melt adhesives, having a softening point in the range of about 60.degree. C to about 110.degree. C prepared by polymerizing a monomer mixture selected from specific amounts of styrene, isobutylene and 1,3-butadiene, where the mole ratio of isobutylene to butadiene is in the range of about 0.5/1 to about 3/1. The resinous material itself is prepared by polymerizing the selected monomers and their required amounts in the presence of a catalyst selected from aluminum chloride and ethylaluminum dichloride and in the presence of a hydrocarbon solvent containing dissolved water.

Abstract: An oxidation resistant polymeric composition comprising the reaction product of some carbon-to-carbon double bond unsaturated polymers and a 1,3-dipolar compound corresponding to the general formula ##SPC1##Wherein R is selected from various alkyl radicals, aromatic radicals, cycloalkyl radicals, phenyl radicals and substituted phenyl radicals.

Abstract: A composition comprising a rubbery copolymer of propylene oxide in admixture with a heat age resisting mixture of a nickel dialkyl dithiocarbamate and an imidazole where the ratio of the carbamate units to imidazole units is in the range of from about 16:1 to about 1:40. The composition has particular utility for providing a rubbery copolymer of propylene oxide having improved resistance to heat aging in a temperature range of about 100.degree.C. to about 170.degree.C.

Abstract: Chlorothio-sulfonamide-modified rubbery terpolymers having a low degree of unsaturation, mixtures of such modified terpolymers with highly unsaturated rubbery polymers and vulcanizates of such mixtures. The vulcanizates are particularly useful in the structure of pneumatic tire sidewalls.

Abstract: A rubbery copolymer of butadiene, styrene and acrylonitrile, if desired, with a tensile strength of about 50 to about 100 psig containing a minor amount of styrene, particularly in combination with selective tackifier resins. Said copolymer is preferably prepared by a step-wise aqueous emulsion polymerization with styrene and modifier being incrementally added. Said rubbery copolymer/tackifier mixture is particularly useful as an adhesive.

Abstract: Polymers of ethylene, an alpha mono-olfin, and ethylidene bicycloheptene which can be sulfur-cured to form elastomers.

Abstract: A textile fabric composite, particularly an industrial belt, prepared by the sequential steps of (A) encapsulating the fibers of a fabric with a polyurethane reaction mixture, (B) drying and at least partially curing said reaction mixture, (C) adhering an overlay of a flexible thermoplastic to one surface of said encapsulated fabric and (D) pressing said thermoplastic into the interstices of said encapsulated fabric under pressure and with the application of heat.

Abstract: Alpha-methyl-p-bromo-styrene prepared by the manipulative steps of brominating poly(.alpha.-methyl-styrene) and subsequently depolymerizing the brominated polymer. The alpha-methyl-p-bromo-styrene has particular utility as a co-monomer for preparing copolymers exhibiting a flame retardancy.

Abstract: A thermoplastic composition suitable as a mold release surface for preparing cast articles which comprises a silane grafted poly(vinyl alcohol) prepared by the method which comprises incrementally reacting a selected silane with the poly(vinyl alcohol) characterized by having a molecular weight in the range of about 5,000 to about 150,000, by having a 4 weight percent aqueous solution viscosity at 20.degree.C in the range of about 5 to about 65 centipoises, and by containing about 70 to about 98 weight percent vinyl alcohol units.

Abstract: An adhesive composition which comprises a mixture ofA. an unvulcanized elastomeric block copolymer having the general configuration A - B - A wherein each A is a nonelastomeric monovinyl aromatic hydrocarbon polymer block and B is an elastomeric conjugated diene polymer block, andB. a compatible thermoplastic tackifying resin containing carbon-to-carbon unsaturation therein and derived from hydrocarbons selected from aliphatic and alicyclic hydrocarbons.

Abstract: A polyurethane composition, resistant to sulfuric acid, prepared by reacting 2,2'-diaminodisulfide with an isocyanate-terminated prepolymer, itself prepared by reacting, in the presence of a 2,6-dialkylated para cresol, at least one polymeric polyol with a diphenyl methane diisocyanate.
