Patent number: 4182716Abstract: 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.Type: GrantFiled: November 8, 1978Date of Patent: January 8, 1980Assignee: Uniroyal, Ltd.Inventors: Andrew A.

Patent number: 4129542Abstract: A novel thermoplastic, elastomeric material is obtained by curing under shear conditions (e.g. in a high shear internal mixer) a blend of vulcanizable rubber (e.g. SBR, EPDM) and a bituminous material (e.g., asphalt) in the presence of a rubber vulcanizing agent (e.g. sulfur or peroxide). The product has a unique combination of elastomeric and thermoplastic properties. It can be processed by conventional thermoplastic methods at elevated temperatures (e.g. extrusion, calendering, vacuum forming) and at normal temperatures possesses good elastomeric properties without the need for subsequent vulcanization. If desired, the material can be re-processed.Type: GrantFiled: February 5, 1976Date of Patent: December 12, 1978Assignee: Uniroyal Ltd.Inventors: Alister F. Matheson, Douglas J. Tosh, Mitchell Borr
