Abstract: Disclosed is an antioxidant fermenting microorganism agent and a polyurethane foam including the same. The antioxidant fermenting microorganism agent is used to generate a substance that is capable of reducing an amount of volatile organic compounds generated from the polyurethane foam and has an antimicrobial ability. The polyurethane foam containing the antioxidant fermenting microorganism according to the present invention can be used as the material for the interior of a vehicle to protect humans from noxious substances causing sick car syndrome.

Abstract: The present invention relates to a process for producing a thermoplastic resin having high impact strength and good surface gloss, which comprises graft copolymerizing at least a vinyl cyanide compound and at least an aromatic vinyl compound for a short period of less than about 3 hours in the presence of rubber latex having high gel content. The rubber latex can be a mixture of two or more rubber latices having different particle size. The graft copolymer has the characteristics such that the degree of the inner occlusion into the resin is decreased and the degree of surface grafting is increased. Thereby, the resulted thermoplastic resin has a very high impact strength and good surface gloss, and the processability is greatly improved. In addition, when the graft copolymer is polymerized the level of coagulum formation is greatly decreased.
