摘要： Diene polymers or copolymers having improved balance between raw polymer viscosity and mixed compound viscosity, useful in tire tread compositions having highly balanced wet traction, rolling resistance, and traction in ice and snow, and fracture properties in the cured and white carbon reinforced states are provided. These diene polymers or copolymers comprise a mixture of diene polymer or copolymer chains containing carbon-tin bonds in the main polymer or copolymer chains and diene polymer or copolymer chains containing terminals derived from hydrocarboxysilane compounds. The diene polymer or copolymers are prepared by first coupling a portion of the living diene polymer or copolymer chains obtained by anionic polymerization using a tin polyhalide coupling agent and then terminating the remaining living diene polymer or copolymer chains using hydrocarboxysilane compounds. The resultant diene polymers or copolymers have improved balance between raw polymer viscosity and mixed compound viscosity when compounded with silica and/or carbon black and cured compositions are useful in tire tread having highly balanced wet traction, rolling resistance, and traction in ice and snow. The polymers can be utilized to form elastomer compositions for tire treads having balanced properties of reduced rolling resistance and wet traction and handling or balanced properties of wet traction and handling and traction in snow and ice.

摘要： Relatively pure tertiaryaminoalkyllithium initiators suitable for anionic polymerization reactions are prepared at low temperatures in an organic ether by reacting an equivalent excess of lithium metal with a tertiaryaminoalkylhalide. The lithium initiators are very stable at moderate temperatures when the ether is replaced by an aliphatic, a cycloaliphatic, or an aromatic solvent. Yields of the initiator in excess of 98% are readily achieved.

摘要： A composite comprises a coating which is adhered to a highly saturated elastomer having a corona discharge activated surface which is chemically fixed by a halogenating agent. A coating such as a paint, a weather-resistant film, etc., or an adhesive layer, is adhered to the activated and fixed surface. Various halogenating agents include N-halohydantoins, N-haloimides, N-haloamides, aqueous chlorine or bromine solutions, and acidified hypochlorite solutions. The composite is useful for EPDM roofing and consumer goods, e.g., a flexible polyurethane paint applied to the sidewalls of tires, as a decorated article, bonded composites, and the like.

摘要： The incorporation of an alkaline earth hydroxide or oxide in a non-nitrogen-containing polymer results in the reduction of carbon monoxide and visible smoke generated during burning of the polymer. The polymer may be an elastomer, (that is a rubber), a thermoplastic, a thermoplastic elastomer, or a thermoset containing from 25 to about 400 parts of the alkaline earth metal compound per 100 parts of the polymer. A small amount of transition metal salts has further been found to greatly reduce the amount of carbon monoxide generated.

摘要： The flammability of acrylonitrile-butadiene-sytrene resin is significantly decreased by adding thereto a combination of a brominated aromatic ether and iron or chromium naphthenate.The brominated aromatic ethers which may be used are illustrated by the generalized structure: ##STR1## in which x is 2 to 5 and y is 0 to 5, provided x plus y equals at least 2. Examples of these compounds include decabromodiphenyl oxide, octabromodiphenyl oxide, hexabromodiphenyl oxide, pentabromodiphenyl oxide or tetrabromodiphenyl oxide.The ABS resins which can be treated include the terpolymer produced by polymerization of acrylonitrile, butadiene and stryene monomers, as well as terpolymers produced by grafting acrylonitrile and styrene on polybutadiene, or blends of the component polymers.
