Title:
RESIN COMPOSITION FOR CROSS-LINKED FOAM MOLDING, CROSS-LINKED FOAM MOLDED ARTICLE, AND METHOD FOR PRODUCTION OF CROSS-LINKED FOAM MOLDED ARTICLE
Document Type and Number:
WIPO Patent Application WO/2010/024458
Kind Code:
A1
Abstract:
Disclosed are: a polymer composition comprising 100 parts by weight of a component (A) shown below and 0.5 to 20 parts by weight of a component (B) shown below; a foaming agent; and a resin composition for cross-linked foam molding, which contains a cross-linking agent. The component (A): an ethylene polymer which meets the following requirements (a1) to (a2): (a1) the density is 860 to 935 kg/m3; and (a2) the melt flow rate (MFR) is 0.1 to 10 g/10 min. The component (B): an ethylene-α-olefin copolymer which meets the following requirements (b1) to (b3): (b1) the density is 890 to 925 kg/m3; (b2) the intrinsic viscosity [η] as measured in a tetralin solution is 4 to 15 dL/g; and (b3) the activation energy of flow (Ea) is less than 50 kJ/mol.
