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

Polyacrylonitrile yog ib qho polymer ntawm acrylonitrile tsim los ntawm kev sib xyaw ua ke ntawm acrylonitrile, methyl acrylate, econonic acid, thiab lwm yam. Nws yog cov khoom siv raw ntawm nitrile (feem ntau hu ua cov plaub cuav). Cov mis tshuaj [CH2 = CH-CN] n, qhov nruab nrab molecular hnyav ntawm cov qauv yog 2.5 × 104 ~ 8 × 104。 Nws yog hmoov dawb ntawm qhov kub ib txwm, nrog rau qhov hnyav tshwj xeeb ntawm 1.14 ~ 1.16. Lub ntsiab lus mos yog 267 ℃ thiab qhov kub thiab txias decomposition yog 230 ℃.
