The preparation of a kind of porous hdlow 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 ale studied in details.It shows that degree of ring formation is increasing with increasing of oxidation temperature and time.Comparing with normal molecular weisht polyacrylonitrile (CMW-PAN) based solid fibers
the oxidation temperature of porous hollow fiber based on UHMW-PAN should be low (<240℃)
