Abstract: A bloom inhibitor which comprises (A) an alkylene oxide adduct of a saponified ethylene-saturated carboxylic acid vinyl ester copolymer, and (B) a polyether compound; a rubber composition comprising a rubber and the bloom inhibitor; and a vulcanized rubber in which blooming is prevented obtained by vulcanizing the rubber composition are provided.

Abstract: A process for producing a flame retardant thermoplastic resin composition which has an excellent flame retardancy while maintaining sufficiently high levels of mechanical properties including tensile property, flexural property and impact resistance which process comprises the following first step and second step:the first step: the step of melt-kneading the following components (A) and (B) to obtain a melt-kneaded composition (AB),the second step: the step of melt-kneading the melt-kneaded composition (AB) and the following component (C) to obtain the flame retardant thermoplastic polyester resin composition:component (A): an impact resistance improver,component (B): a flame retarder,component (C): a thermoplastic polyester resin.

Abstract: A modifier for resin and rubber of which an active ingredient is a reaction product of a styrene-maleic anhydride copolymer (A) with a poly(alkylene oxide) monoalkyl ether (B), and/or a metal salt thereof, which modifier improves processability and properties of resins or rubbers. For example, the modifier provides resins or rubbers with antistatic properties. It also enhances the dispersibility of additives, e.g., a flame retardant or fillers incorporated in the resin or the rubber, and provides resins or rubbers with, for example, excellent flame retardancy and prevents the additive or the filler from blooming.

Abstract: A flame retardant thermoplastic resin composition which comprises (A) 50 to 90% by weight of a thermoplastic resin which is the base polymer and 50 to 10% by weight of a total of (B) a nitrogen-containing condensed phosphoric acid compound, (C) a comb-like polymer consisting of a polyethylene main chain and a polyoxyalkylene side chain and (D) a metal-containing compound having a carbonization accelerating effect, the amounts of the components (B), (C) and (D) being 5 to 49% by weight, 1 to 15% by weight and 0 to 10% by weight, respectively, in which the total amount of the components (A), (B), (C) and (D) is 100% by weight; a process for producing the composition; a flame-retardant consisting of the components (B), (C) and (D); and a process for producing the flame-retardant.
