Abstract
PURPOSE: A composition capable of providing a molded article having both transparency and low aldehyde content, comprising chips obtained by extruding a crystallized polyethylene terephthalate and a speciic crystallized polyethylene terephtalate in molten state under a fixed condition.
CONSTITUTION: (A) A polyethylene terephthalate having a crystallinity of ≥40% to <70%, an acetaldehyde content of <20ppm, and a main repeating unit of polyethylene terephthalate and (B) a polyethylene terephthalate having a crystallinity of ≥35% to <75%, an acetaldehyde content of <20ppm and a main repeating unit of polyethylene terephthalate, are extruded in molten state under conditions satisfying the formula [T is an extrusion melt temperature (°C) of polyethylene terephthalate (°C); Tm is a melting temperature of a polyethylene terephthalate (°C); t is a retention time during the extrusion (minute)] to give chips. The chip compound consists of 99W75wt% component A and 1W25wt% component B.
