    摘要： The present invention is related to a method of manufacture of a graft copolymer latex and its dried powder including a step of manufacture of a latex using a reactive surfactant for a surfactant in manufacturing of the graft copolymer latex containing acrylic polymers and a step of manufacture of dried powder in which the graft copolymer latex manufactured in the above step of manufacture of a latex is sprayed and dried. The method according to the present invention is effective in that it is possible to provide for dried powder of a graft copolymer latex having a low moisture content and a high powder density and to provide for a thermoplastic resin composition containing the above latex having superior luster, tensile strength, and thermal stability.

    摘要： A method for preparing a weatherable thermoplastic resin, having superior weatherability and colorability and a weatherable thermoplastic resin prepared by the method are provided. The method includes preparing a seed by adding a water-soluble initiator to either an aromatic vinyl compound or a (meth)acrylic acid alkyl ester to obtain a first compound and performing polymerization with respect to the first compound; preparing an alkyl acrylate rubber polymer by adding an alkyl acrylate monomer, a first emulsifier of pH about 3 to about 9, and an oil-soluble initiator to the seed to obtain a second compound and performing polymerization with respect to the second compound; and preparing graft copolymer by adding the aromatic vinyl compound, a vinyl cyanide compound, a second emulsifier of pH about 9 to about 13, and the oil-soluble initiator to the alkyl acrylate rubber polymer to obtain a third compound and performing graft copolymerization with respect to the third compound.
