Abstract

PURPOSE: To provide the titled foam having uniform fine closed cells and excellent heat resistance, mechanical strength, elastic recovery, etc., by a method wherein a blocked polyether ester is crosslinked and then expanded by heating.
CONSTITUTION: A blocked polyether ester is produced which consists of 20W 70wt% short-chain polyester unit (A) (composed of at least 50mol% butylene terephthalate unit) and 80W30wt% long-chain polyether ester unit (B) [composed mainly of poly (alkylene oxide) glycol having a number-average MW of 500W 6,000]. A blowing agent and a crosslinking promotor are mixed with said blocked polyether ester. The mixture. is then crosslinked by means of ionizing radiation and expanded by heating it to a temp. not lower than the decomposition temp. of the blowing agnet to produce the desired foam having a chemically crosslinked structure in which gel fraction measured on tetralin-insoluble matter at 120°C is 5wt% or more.
