Title
(EN) TUBULAR POLYMERIZATION REACTORS AND POLYMERIZATION PROCESS USING SAME
(KO) 관형 중합반응기 및 이를 사용하는 중합방법
Abstract
(EN)

Tubular reactor apparatus and processes are provided for improved polymerization including using chain transfer agents and multiple monomer feeds spaced lengthwise along the tubular reactor providing high conversions of monomer into polymer. The invention also relates to polymers made from such a tubular reactor apparatus and processes including those polymers having a low haze value, a density over 0.92 g/cm3 and/or having terminal carbonyl groups. The apparatus and methods uncouple or reduce the dependency between the monomer concentration and transfer agent concentration. The uncoupling in other embodiments may also be varied leading to multiple desirable effects.

(KO) 본 발명은 쇄 전달제 및 관형 반응기를 따라 세로방향으로 이격된 다성분 단량체 공급물을 사용하는 것을 포함하여 단량체의 중합체로의 높은 전환을 제공하는 개선된 중합을 위한 관형 반응기 장치 및 방법을 제공한다. 본 발명은 또한 낮은 헤이즈(haze) 값, 0.93g/cm3 초과의 밀도 및/또는 종지 카보닐기를 갖는 중합체를 비롯한 상기 관형 반응기 및 방법으로부터 제조한 중합체에 관한 것이다. 상기 장치 및 방법은 단량체 농도와 전달제 농도 사이의 의존성을 언커플링(uncoupling)나 감소시킨다. 다른 양태에 있어서 언커플링은 또한 여러 가지 바람직한 효과를 유발하도록 변할 수도 있다.
