Document Type and Number:
WIPO Patent Application WO/2013/100448
Kind Code:
A1
Abstract:
The present invention relates to an acrylonitrile styrene acrylate (ASA) graft copolymer having a core-shell structure, and a method for manufacturing same, wherein the core of the ASA graft copolymer is a multi-core rubber copolymer in which alkyl acrylate monomers are sequentially polymerized, and the shell is formed by a styrene monomer and an acrylonitrile monomer polymerizing with the core. The ASA graft copolymer resin is manufactured by the steps of manufacturing a multi-core rubber polymer latex by sequentially polymerizing the alkyl acrylate monomers; and forming a shell layer by graft-polymerizing the styrene monomer and the acrylonitrile monomer with the multi-core rubber polymer. The ASA resin according to the present invention has superior shock resistance, weather resistance, and coloring properties.
