Title:
オリゴマーが低減したポリ(トリメチレンテレフタレート)ペレット及びオリゴマーの低減を測定する方法
Document Type and Number:
Japanese Patent JP2012519756
Kind Code:
A
Abstract:
The invention relates to the preparation of poly(trimethylene terephthalate) polymer pellets with reduced oligomers and a process for measuring the reduction of oligomers in PTT polymer which occurs when the polymer is subjected to a heat source. This reduction allows for lower polymer blooming due to reduction of oligomers in the polymer.
