Title:
EXPANSION MOLDED BODY AND METHOD FOR PRODUCING EXPANSION MOLDED BODY
Document Type and Number:
WIPO Patent Application WO/2010/073998
Kind Code:
A1
Abstract:
Disclosed is an expansion molded body which is formed from a polyolefin resin composition (I) containing (A) a polyvinyl alcohol fiber, (B) a polyolefin resin, and (C) a modified polyolefin resin modified with an unsaturated carboxylic acid and/or a modified polyolefin resin modified with an unsaturated carboxylic acid derivative. The content of the polyvinyl alcohol fiber (A) is 1-70% by mass, the content of the polyolefin resin (B) is 20-98.5% by mass, and the content of the modified polyolefin resin (C) is 0.5-40% by mass, respectively, relative to the total mass of the polyvinyl alcohol fiber (A), the polyolefin resin (B) and the modified polyolefin resin (C). The expansion ratio of the expansion molded body is within the range of 1.3-5 times. The polyvinyl alcohol fiber (A) contains (A-I) a polyvinyl alcohol filament and (A-II) a sizing agent, and the content of the sizing agent (A-II) is 0.1-10 parts by mass relative to 100 parts by mass of the polyvinyl alcohol filament (A-I).
