COMPOSITION FOR FOAM, PROCESS FOR PRODUCING THE SAME, AND FOAM MOLDED PRODUCT

摘要

The use of a composition for a foam containing (A) 1,2-polybutadiene having a glass transition temperature (Tg) of -60°C to +10°C, (B) a vinyl-cis-butadiene rubber (VCR), (C) a thermoplastic polymer other than the above components (A) and (B), (D) a foaming agent, and (E) a crosslinking agent can provide a composition for a foam, which has an excellent thickness accuracy, has a suitable level of hardness, has excellent smoothness, and, at the same time, has an improved thickening effect during hot melting on such a level that there is no excessive flow upon exposure to heat (i.e., sensitivity to temperature is so low that color mixing is not significant), and excellent processability, and a molded product such as a shoe sole using the composition.
