摘要
本文用凝胶渗透色谱法(GPC)测量聚酯(PET)切片的分子量和分子量分布,对高速纺聚酯切片的可纺性进行了研究,对今后纺丝具有指导意义。
In this thesis, the method of gel permeation chromatography was used to measure the PET molecular weight and its distribution, and the spinnabililty of polyester was studied, which had a guiding significance in the spinning field.
