Polyacrylonitrile Nrog Cas 25014-41-9 yog dab tsi?

Polyacrylonitrile yog ib tug polymer ntawm acrylonitrile tsim los ntawm copolymerization ntawm acrylonitrile, methyl acrylate, econonic acid, thiab lwm yam. Nws yog raw khoom ntawm nitrile (feem ntau hu ua wool dag). Cov tshuaj formula [CH2 = CH-CN] n, qhov nruab nrab molecular hnyav ntawm cov qauv yog 2.5 × 104 ~ 8 × 104. Nws yog cov hmoov dawb ntawm qhov kub thiab txias, nrog lub ntiajteb txawj nqus ntawm 1.14 ~ 1.16. Lub softening point yog 267 ℃ thiab decomposition kub yog 230 ℃.
