摘要： An anionic polymerization initiator includes the C-lithio reaction product of an organolithium compound and a tertiary-amino allyllithium or a tertiary-amino xylyllithium. When used in an anionic polymerization, a functional group from the initiator is incorporated onto the head of the growing polymer and a lithium atom is incorporated at the "living" end of the polymer chain prior to quenching. The initiator may be used to polymerize a monomer(s) including diolefin monomers, monovinyl aromatic monomers and trienes, and the living ends of the polymers are effectively maintained even at temperatures of up to 300.degree. F. and higher. Such polymers exhibit an increased efficiency in coupling termination reactions, and products prepared from such polymers exhibit improved hysteresis characteristics. Products such as tires and the like can be prepared from such polymers and from vulcanizable elastomer compositions employing the polymers.

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.
