POLYACRYLONITRILE (PAN) POLYMERS WITH LOW POLYDISPERSITY INDEX (PDI) AND CARBON FIBERS MADE THEREFROM

좁은 분자량 분포를 갖는 폴리아크릴로니트릴(PAN) 폴리머를 합성하는 방법이 기술된다. 바람직한 PAN 폴리머는 약 2 이하의 PDI(Mw/Mn)를 갖는다. 이러한 PAN 폴리머는 특별한 RAFT(가역적 첨가-분절화 사슬 전달(Reversible Addition-Fragmentation Chain Transfer)) 제제를 사용하여 제어된/리빙 라디칼 중합에 의해 합성된다. 또한, 낮은 PDI를 갖는 PAN 폴리머로부터 탄소 섬유를 제조하는 방법이 기술된다.

description	좁은 분자량 분포를 갖는 폴리아크릴로니트릴(PAN) 폴리머를 합성하는 방법이 기술된다. 바람직한 PAN 폴리머는 약 2 이하의 PDI(Mw/Mn)를 갖는다. 이러한 PAN 폴리머는 특별한 RAFT(가역적 첨가-분절화 사슬 전달(Reversible Addition-Fragmentation Chain Transfer)) 제제를 사용하여 제어된/리빙 라디칼 중합에 의해 합성된다. 또한, 낮은 PDI를 갖는 PAN 폴리머로부터 탄소 섬유를 제조하는 방법이 기술된다. A method for synthesizing polyacrylonitrile (PAN) polymer with a narrow molecular weight distribution is disclosed. The preferred PAN polymer has a PDI (Mw/Mn) of about 2 or less. Such PAN polymer is synthesized by controlled/living radical polymerization using a special RAFT (Reversible Addition-Fragmentation Chain Transfer) agent. Also disclosed is a method for producing carbon fibers from PAN polymer with low PDI.
