摘要：

The preparation of a kind of porous hollow oxidation fiber based on ultrahigh molecular weight polyacrylonitrile ( UHMW-PAN) as precursor is presented. The effects of preparation technology conditions, oxidation temperature and oxidation time, on degree of ring formation of porous hollow oxidation fiber are studied in details. It shows that degree of ring formation is increasing with increasing of oxidation temperature and time. Comparing with normal molecular weight polyacrylonitrile (CMW-PAN) based solid fibers, the oxidation temperature of porous hollow fiber based on UHMW-PAN should be low (< 240 degreesC) and oxidation time should be short (< 2 h).
