Abstract
An expandable composition for non-crosslinked foam comprising: (a) 80 to 99% by weight of a 1-butene copolymer, (b) 20 to 1% by weight of an ethylene polymer, and (c) a blowing agent, the percentages being based on the total weight of the 1-butene copolymer and the ethylene polymer.

An expandable composition for non-crosslinked foam comprising:
- (a) 80 to 99% by weight of a 1-butene copolymer,
- (b) 20 to 1% by weight of an ethylene polymer containing at least 90 mole% of polymerized units of ethylene, and
- (c) a blowing agent,
- the percentages being based on the total weight of the 1-butene copolymer and the ethylene polymer wherein the 1-butene copolymer is composed of at least 70 mole% of polymerized units of 1-butene and not more than 30 mole% of polymerized units of an alpha-olefin having 2 to 20 carbon atoms other than 1-butene.
