Document Type and Number:
WIPO Patent Application WO/2001/081461
Kind Code:
A1
Abstract:
A noncrystalline polyolefin resin composition which has significantly improved impact resistance while retaining intact transparency due to an impact modifier produced from easily available materials by an ordinary polymerization method. The composition contains as the impact modifier a core-shell elastomer obtained by graft-polymerizing in the presence of a conjugated diene copolymer rubber a monomer mixture comprising: an alkyl (meth)acrylate in which the alkyl has 3 to 8 carbon atoms, an alkyl (meth)acrylate in which the alkyl has up to 2 carbon atoms, or a vinyl cyanide compound; and an aromatic vinyl monomer in a specific proportion.
