Abstract

말단이 개방된, 실질적으로 관상의 폴리에스테르 초기중합체 펠릿은 반응 부산물 확산 특성을 개선시키므로써 크게 개선된 고체 상태 중합 속도를 제공한다.

Description

낮은 내확산성 초기중합체 펠릿으로 폴리에스테르를 고체 상태 중합시키는 방법(SOLID STATE POLYMERISATION OF POLYESTERS WITH LOW DIFFUSION RESISTANCE PREPOLYMER PELLETS)
본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음

Claims (10)

  1. 실질적으로 관상의 말단이 개방된 펠릿으로 형성된 폴리에스테르 초기중합체로 구성되는 높은 분자량 폴리에스테르로 고체 상태 중합될 수 있는 개선된 가스 확산 특성을 갖는 폴리에스테르 초기중합체 펠릿.
  2. 제1항에 있어서, 초기중합체가 30℃의 온도에서 60 : 40 페놀 : 테트라클로로에탄 용매 시스템내에서 측정되는 바와 같이 0.25dl/g 내지 0.75dl/g 범위내 고유 점도를 갖는 펠릿.
  3. 제1항 또는 제2항에 있어서, 양 말단에서 개방되어, "O"-모양 단면을 갖는 펠릿.
  4. 제1항 또는 제2항에 있어서, 양 말단에서 개방되어 있고, 측면이 개방되고, "C"-모양 단면을 갖는 펠릿.
  5. 제4항에 있어서, 측면 개방구가 펠릿 직경의 1/5 보다 더 좁은 펠릿.
  6. 제4항에 있어서, 측면 개방구가 0.01 내지 10mm 범위내 크기의 갭을 제공하는 펠릿.
  7. 제6항에 있어서, 갭 크기가 0.1 내지 0.4mm 범위내인 펠릿.
  8. 제1항 내지 제7항 중 어느 한 항에 있어서, 폴리에스테르가 폴리(에틸렌 테레프탈레이트) 또는 폴리(에틸렌 나프탈레이트)인 펠릿.
  9. 폴리에스테르 초기중합체가 실질적으로 관상의 용융된 스트랜드를 형성하도록 고안된 다이를 통해 압출되고, 이 용융된 스트랜드가 켄칭되고나서, 고체 상태 중합체 적합한 크기 및 모양의 말단이 개방된 펠릿으로 절단되는 것을 특징으로 하는, 용융 중합시키고 나서, 펠릿으로 압출되므로써 펠릿화된 폴리에스테르 초기중합체를 제조하는 방법.
  10. 고체 상태 중합체 의한 폴리에스테르 중합체의 제조에 있어서, 제1항 내지 제8항 중 어느 한 항에 청구되거나, 제9항에서 청구된 바와 같은 방법에 의해 제조된 폴리에스테르 초기중합체 펠릿의 용도.
