Abstract
An improved shaped article can be prepared from a blockcopolyetherester by (a) mixing the same with poly(butylene terephthalate) at a temperature of about 200.degree. to about 230.degree. C. whereby fine fragments of poly(butylene terephthalate) which maintains its own crystalline phase are dispersed in the matrix of the blockcopolyetherester, and (b) molding the mixture at a temperature below the melting point of the poly (butylene terephthalate). The addition of an ester wax and/or a calcium soap improves the extrusion-moldability of the mixture.
