At room temperature, PBT is resistant to weak acids, weak bases, water, and aqueous solutions of neutral and acid salts. PBT is non-resistant to strong acids,
oxidizing acids, strong bases, ketones and phenols.
Above 6O, PBT becomes increasingly sensitive to univalent alcohols,aromatic substances, and ketones.
另外,你可以借用常溶解PET的溶劑:苯酚與四氯乙烷的混合物(質(zhì)量比3:2或1:1)
PBT為乳白色半透明到不透明、結(jié)晶型熱塑性聚酯。具有高耐熱性、韌性、耐疲勞性,自潤(rùn)滑、低摩擦系數(shù),耐候性、吸水率低,僅為0.1%,在潮濕環(huán)境中仍保持各種物性(包括電性能),電絕緣性,但體積電阻、介電損耗大。耐熱水、堿類、酸類、油類、但易受鹵化烴侵蝕,耐水解性差,低溫下可迅速結(jié)晶,成型性良好。缺點(diǎn)是缺口沖擊強(qiáng)度低 ,成型收縮率大 。故大部分采用玻璃纖維增強(qiáng)或無機(jī)填充改性,其拉伸強(qiáng)度、彎曲強(qiáng)度可提高一倍以上,熱變形溫度也大幅提高?梢栽140℃下長(zhǎng)期工作,玻纖增強(qiáng)后制品縱、橫向收縮率不一致,易使制品發(fā)生翹曲,

六氟異丙醇
n貴
三氟乙酸好像也可以,比樓上的那位兄弟便宜,還可以用鄰氯苯酚。
???
你強(qiáng),
苯酚與四氯乙烷的混合物(質(zhì)量比1:1)能溶解
四氫呋喃溶解不了
