He aha ka Polyacrylonitrile me Cas 25014-41-9?

ʻO ka Polyacrylonitrile kahi polymer o ka acrylonitrile i hoʻokumu ʻia e ka copolymerization o ka acrylonitrile, methyl acrylate, econonic acid, a me nā mea ʻē aʻe. ʻO ia ka mea maka o ka nitrile (i ʻike nui ʻia ʻo ka huluhulu artificial). ʻO ke ʻano kemika [CH2=CH-CN] n, ʻo ke kaumaha molekala awelika o ke ʻano he 2.5 × 104 ~ 8 × 104. He pauka keʻokeʻo ia ma ka mahana maʻamau, me ke kaumaha kikoʻī o 1.14 ~ 1.16. ʻO ke kiko palupalu he 267 ℃ a ʻo ka mahana decomposition he 230 ℃.
