摘要:
Disclosed herein are a polyimide-polybenzoxazole copolymer, a method for preparing thereof and a gas separation membrane comprising the same. More specifically, provided are a polyimide-polybenzoxazole copolymer simply prepared through thermal-rearrangement performed by thermally treating a polyimide-poly (hydroxyimide) copolymer as a precursor, a method for preparing the same, and a gas separation membrane comprising the same. The copolymer shows superior gas permeability and gas selectivity, thus being suitable for use in gas separation membranes in various forms such as films, fibers or hollow fibers. The gas separation membrane thus prepared can advantageously endure even harsh conditions such as long operation time acidic conditions and high humidity due to the rigid polymer backbone present in the copolymer.
摘要(中):
本文公开了聚酰亚胺 - 聚苯并恶唑共聚物,其制备方法和包含其的气体分离膜。 更具体地,提供了通过热处理作为前体的聚酰亚胺 - 聚(羟基酰亚胺)共聚物,其制备方法和包含该聚酰亚胺 - 聚(羟基酰亚胺)共聚物的前驱体的热重排简单制备的聚酰亚胺 - 聚苯并恶唑共聚物。 该共聚物具有优异的气体渗透性和气体选择性,因此适用于各种形式的气体分离膜,例如膜,纤维或中空纤维。 由此制备的气体分离膜可有利地承受由共聚物中存在的刚性聚合物骨架导致的恶劣条件,例如长时间的酸性条件和高湿度。
