  • Patent number: 4192790
    Abstract: The viscosity of synthetic and/or natural elastomers is markedly reduced by incorporation of a particulate, finely-divided basic zinc methacrylate-type adjuvant, without adversely affecting the physical properties of the final vulcanizates. This viscosity reduction allows higher levels of fillers and other rubber compounding materials to be used for improved physical properties, while maintaining the level of compound viscosity necessary for processing.

  • Patent number: 4182716
    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.

  • Patent number: 4129542
    Abstract: 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.
