METHODS FOR PREPARING OF WEATHERABILITY THERMOPLASTIC RESIN |
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. |
