POLYACRYLONITRILE POLYMER, PROCESS FOR PRODUCTION OF THE POLYMER, PROCESS FOR PRODUCTION OF PRECURSOR FIBER FOR CARBON FIBER, CARBON FIBER, AND PROCESS FOR PRODUCTION OF THE CARBON FIBER

摘要

The invention includes a polymer composed mainly of acrylonitrile and the nitrile-based polymer provides the following [a] to satisfy the requirements of one or more kinds selected from [d] polyacrylate. [A] is a gel permeation chromatography (GPC), only the Z-average molecular weight (Mz) is 800,000 to 600, as measured by method and polydispersity (Mz / Mw) (Mw denotes a weight average molecular weight) is 3.0 to 10.0 . [B] Z + 1-average molecular weight of only the GPC method (Mz + 1) are 300 million to 1000 as measured by a high, and a polydispersity (Mz + 1 / Mw) is 6.0 to 25.0. The Mzm is only 400,000 to 100, as measured by multi-angle light scattering spectrophotometry high, it is 3.0 to 10.0 polydispersity (Mzm / Mwm) - [c] gel permeation chromatography. Z is the average radius of rotation (Rz), as measured by multi-angle light scattering spectrophotometry is from 25 to 45 ㎚, and a 1.3 to 2.5 ratio (Rz / Rw) and the weight average of the turning radius - [d] gel permeation chromatography. ; Nitriles, polymers, carbon fibers, polyacrylonitrile
