POLYESTER COMPOSITION IMPROVED IN FLUIDITY

摘要

The invention relates to a resin composition which comprises (A) polytetramethylene terephthalate and (B) an aromatic polybasic acid ester of the formula (1): ...(1) wherein X represents -COOR (R being an alkyl group havirg 1 to 12 carbon atoms), n represents an integer of 3 to 4 and the alkyl groups R in X may be the same as or different from one another. Such a composition has improved fluidity and is suitable for thin walled moldings or articles of complicated shapes, in engineering plastics such as for electronic components.
