    摘要： Provided are a method of producing a graft copolymer, the method involving subjecting a radically polymerizable monomer to living radical graft polymerization with a rubber component formed of a natural rubber and/or a synthetic diene-based rubber in an aqueous medium in the presence of a polymerization control agent, a rubber composition containing the graft copolymer obtained by the method, and a tire obtained by using the rubber composition in any one of its tire members. Further provided are a method of efficiently producing a graft copolymer, the method involving subjecting a radically polymerizable monomer, in particular, a functional group-containing radically polymerizable monomer to living radical graft polymerization with the natural rubber and/or the synthetic diene-based rubber, a rubber composition containing the graft copolymer obtained by the method and excellent in, for example, low heat generating property, wear resistance, and fracture characteristic, and a tire obtained by using the rubber composition in any one of its tire members and having the above-mentioned properties.

    摘要： A powdery flame retardant which is obtained by mixing a flame retardant which is liquid or a viscous solid at ordinary temperature with an inorganic fibrous substance to adhere or adsorb the retardant to the fibrous substance, and which comprises 5 to 70 wt. % the flame retardant and 95 to 30 wt. % the fibrous substance. The powdery flame retardant can be easily handled because it is a powder, and is obtained by a simple and industrially advantageous method. It produces a remarkable effect that the performance of the liquid or viscous flame retardant is not impaired.
