摘要： A method for manufacturing pourable pulverulent rubber-filler mixtures starting from rubber solutions is disclosed. In this method, the filler is dispersed in an organic solvent and then mixed with a rubber solution to obtain a stable rubber-containing filler dispersion. The dispersion is then introduced into hot water containing a dispersed filler and subjected to high shear forces, causing the organic solvent to simultaneously be largely distilled off. After the rubber-containing filler dispersion has been completely added, an aqueous filler dispersion is added, water is removed from the precipitated rubber-filler mixture, and the product mixture is dried under constant agitation.

摘要： A method and composition are disclosed wherein guayule rubber is fractionated into desirable weight average molecular weight fractions by a desired solvent system. Oftentime, a plurality of fractionating steps is utilized wherein the desirable molecular weight rubber fraction is precipitated or extracted. High weight average molecular weight rubbers having usually less than 4% by weight of resin content therein are generally desirable because of their favorable physical properties.

摘要： A method for preparing essentially color-free, stabilized polymers of conjugated dienes or vinyl aromatic hydrocarbons or copolymers of conjugated dienes and vinyl aromatic hydrocarbons involves a first stage in which a living polymer of a conjugated diene or vinyl aromatic hydrocarbon or copolymer of a conjugated diene and a vinyl aromatic hydrocarbon is prepared by anionically polymerizing the conjugated diene or vinyl aromatic hydrocarbon, or copolymerizing the conjugated diene and the vinyl aromatic hydrocarbon using a lithium-based catalyst and an inert hydrocarbon diluent. Then, the living polymer or copolymer is terminated by the addition of a suitable terminating agent. Following the termination procedure, boric acid is added to the polymer of copolymer in a sufficient amount to prevent or substantially reduce color formation. Then, stabilizing agents are added to the polymer or copolymer and the polymer or copolymer is recovered from the diluent.
