    摘要: TERMINALLY REACTIVE POLYMERS ARE PRODUCED BY OZONIZING HIGH MOLECULAR WEIGHT POLYMERS OF BRANCHED CONJUGATED DIOLEFINS SUCH AS ISOPRENE AND REACTING THE OZONIZED PRODUCTS WITH MODIFYING COMPOUNDS SUCH AS HYDRAZINE, HYDROXYLAMINE AND DIHYDRAZINO COMPOUNDS. THE REACTIVE POLYMERS ARE LOW MOLECULAR WEIGHT MATERIALS HAVING TERMINAL HYDRAZONE, OXIME AND HYDRAZOLE GROUPS; THEY REACT WITH POLYFUNCTIONAL COMPOUNDS SUCH AS DIISOCYANATES OR EPOXY RESINS TO FORM CROSS-LINKED STRUCTURES.

    摘要: A vulcanized composite laminate comprises a first layer of compounded EPDM rubber and a second compounded layer of butadiene-styrene rubber, a polybutadiene rubber or a blend of polybutadiene rubbers. The layers are bonded by depositing between them, prior to vulcanization, a graft copolymer consisting of an ethylene-propylene-ethylidene norbornene copolymer onto which has been polymerized butadiene and styrene; and a method of forming such composite rubber laminates.

    摘要: Natural graphite-reinforced, cyclized butadiene elastomers are prepared by mixing a homopolymer or copolymer of butadiene and a monoolefinic monomer with natural graphite, curing this mixture with an organic peroxide or mononuclear quinone and thereafter cyclizing the cured mixture by heating at a temperature of 350*700*F. The natural graphite-reinforced, cyclized butadiene polymers are hard, infusible, thermoset materials which have outstanding physical properties, particularly modulii, and resistance to air oxidation, inorganic acids and other chemicals, and overall aging at elevated temperatures.
