PURPOSE:To obtain the title composition providing foam having large plasticizing ability, high productivity, excellent appearance, adhesiveness, pintability, etc., by blending an olefin-based resin with liquid polybutene, liquid polyisobutylene and a blowing agent of thermal decomposition type. CONSTITUTION:100pts.wt. olefin-based resin (e.g. PE, PP or ethylene-propylene copolymer) is blended with preferably 0.2-15pts.wt. liquid polybutene and/or liquid polyisobutylene and further a blowing agent of thermal decomposition type to give the aimed composition. |
