摘要： Rubber curing agents such as quinoids are compounded to achieve a uniform or homogeneous distribution thereof in a rubber composition. The quinoid curing agents are initially solubilized in an organic polar solvent and then mixed with the rubber or rubber masterbatch. The organic polar solvent is then removed. A uniform fine distribution of the curing agent results in improved physical properties. The process is an improvement in that it does not require the rubber masterbatch be dissolved in a nonpolar solvent. The present invention is particularly suitable as a sealant composition for tires.

摘要： Novel solid supported anionic polymerization initiators that are multiply metalated with Group IA alkali metal atoms are provided and employed to produce extremely high molecular weight branched diene polymers. The initiators are prepared by metalating a particle comprising a thermoplastic polymer or a cured elastomer in the presence of a polar coordinator. The polymers obtained by anionic polymerization employing the initiators are multiply branched, with a polymer chain covalently attached to the particle at virtually every metalation site. The macro-branched polymers exhibit desirable properties, such as an extremely high molecular weight, a controlled molecular weight distribution, T.sub.g and vinyl content, and the ability to readily absorb hydrocarbon solvents and oils. The polymers are easily compounded to form vulcanizable elastomeric compounds and articles that have excellent resistance to wear and tear and exhibit reduced hysteresis properties.

摘要： Poly (vinyl sulfoxide)- and (vinyl sulfoxide)-capped elastomers made by capping a lithium terminated elastomer (such as a lithium terminated styrene-butadiene rubber) with more than 0.5 equivalent of vinyl sulfoxide monomer provide compounded elastomer vulcanizates of lowered hysteresis characteristics. Such low hysteresis vulcanizates are useful in making road-contacting tread components of pneumatic tires. Tires with such tread components exhibit low rolling resistance and reduced heat build-up during use.

摘要： A process for the rapid bulk polymerization of polybutadiene/nylon-6 block copolymers comprises the steps of preparing a mixture comprising from about 100 to about 50 parts by weight of a low molecular weight polybutadiene terminated by an isocyanate or isothiocyanate and end-capped with caprolactam providing a stable imide type terminated polymer, with from about 0 to about 50 parts by weight of a dry non-cold flowing rubber neutralized with caprolactam, charging the polymer mixture without hydrolyzing the end-capped polybutadiene to a reaction vessel with caprolactam and polymerizing the caprolactam at a temperature sufficient to flash off any solvents introduced during the step of preparing to form a block copolymer with the end-capped polybutadiene. The process of the present invention is also applicable to the rapid polymerization of other block copolymers formed from anionically polymerized cold flowing rubbers terminated by a compound selected from the group consisting of isocyanates and isothiocyanates and end-capped with an amide containing compound providing a stable imide type terminated rubber and mixed with a non-cold flowing rubber terminated with an amide containing compound which mixture is then charged to a reaction vessel without hydrolyzation with a monomer having an active hydrogen other than a monomer utilized to form a polymer present in the polymer mixture and polymerizing the monomer at a temperature sufficient to flash off any solvents introduced during the step of preparing.
