Abstract
PURPOSE: A fiber glass with a specific fiber-length distribution is included in polyethyene terephthalate to produce a composition giving moldings with high mechanical properties, especially high tenacity and reduced warpage.
CONSTITUTION: A polyester resin containing more than 80mol% of ethylene terephthalate recurring units and a fiberglass bundle with a cut length of more than 2mm, fiber diameter of less than 12μ and filament count of 150W1,000 are melt kneaded using a kneader with the space cross section less than 1/3 that of the feeding part and the length more than 50mm to produce the composition in which the fraction of less than 0.1mm long fibers is less than 15wt% on the basis of the total amount of the fibers, longer than 0.4mm fibers are (55W0.77x) where x is the percentage of the fiberglass added based on the total composition and fibers of more than 15 in average length/fiber diameter are 8W60wt%.
