摘要： A new class of antiozonant compounds, namely tris(N-alkyl-p-phenylenediamino)-1,3,5-triazine compounds, are incorporated into thermosetting compositions having at least one highly unsaturated rubbery polymer and at least one other elastomer having lesser unsaturation, such as EPDM. Thermosetting compositions are most useful as tire sidewall compositions which may be preferably cured with blends of organic peroxide and sulfur donor accelerators.

摘要： Disclosed is a novel polybutadiene or butadiene-styrene copolymer based gum plastic having excellent impact strength and weather aging resistance and a method for its preparation. The ABS composition of the invention is a matrix of a polymer of at least one monoethylenically unsaturated monomer and a graft copolymer comprising a graftable rubber substrate which is formed from a mixture of an at least partially cross-linked pre-grafted polybutadiene or SBR spine latex, and a low-gel elastomer which has been at least partially cross-linked during the preparation of the product. Within certain ratios of cross-linked spine to low-gel spine, significant improvements in impact strength and weather aging resistance are achieved. In the method of preparation, the latex, monomers and low-gel elastomer, are converted directly to the final product by a conventional suspension polymerization process.

摘要： Disclosed is a novel polybutadiene or butadiene-styrene copolymer based gum plastic having excellent impact strength and a method for its preparation. The use of small particle size (SPS) spine latex in a latex-suspension process gives unexpectedly good properties by yielding an ABS with at least about 85% of the rubber present as particles within a specified and relatively narrow size range, i.e., 0.04-0.25.mu. and having a number average particle size less than 0.14.mu.. In the method of preparation, the latex spine and monomers are converted directly to the final product by a conventional suspension process.
