Abstract:
1. A polyester elastomer foam comprising a polyester elastomer composition containing a polyester elastomer having a melting point of 180 to 240° C. and an epoxy-modified polymer, wherein the content of the epoxy-modified polymer in the polyester elastomer composition is 0.5 to 4.0 parts by weight relative to 100 parts by weight of the polyester elastomer, wherein the epoxy-modified polymer is at least one polymer selected from an epoxy-modified acrylic polymer and an epoxy-modified polyethylene, having a weight average molecular weight of 5,000 to 100,000 and an epoxy equivalent of 100 to 3000 g/eq, wherein the polyester elastomer foam has a cell structure having an average cell diameter of 60 to 140 μm.
