저점도 폴리에스테르의 제조방법Process for producing low viscosity polyester

본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음Since this is an open matter, no full text was included.

Claims (2)

점도가 낮은 폴리에스테르를 제조함에 있어서, 통상의 폴리에스테르 용융물에다 이에대해 0.05∼10중량％의 디메틸테레프탈레이트를 첨가하여 폴리에스테르의 점도를 강하시켜서 연속적으로 제조함을 특징으로 하는 저점도 폴리에스테르의 제조방법.In preparing low viscosity polyesters, low viscosity polyesters are prepared by adding 0.05 to 10% by weight of dimethyl terephthalate to ordinary polyester melts to lower the viscosity of the polyesters. Manufacturing method. 제1항에 있어서, 상기 디메틸테르프탈레이트는 폴리에스테르 용융물의 중합반응후 방사공정전에 투입함을 특징으로 하는 저점도 폴리에스테르의 제조방법.The method of claim 1, wherein the dimethyl terphthalate is introduced into the polyester melt before the spinning step after the polymerization reaction of the melt. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
