聚亚芳基醚砜(PAES)聚合物
摘要：
一种聚(芳基醚砜)聚合物[(t-PAES)聚合物，在下文中]，其中大于70％摩尔的重复单元是具有式(St)的重复单元(Rt)：-E-Ar1-SO2-[Ar2-(T-Ar3)n-SO2]m-Ar4-(式St)其中：n和m，彼此相同或不同，独立地是零或1至5的整数，Ar1、Ar2、Ar3和Ar4的每一个彼此相同或不同并且在每次出现时是芳香族部分，T是键或任选地包含一个或多于一个杂原子的二价基团；-E具有式(Et)，其中每个R’，彼此相同或不同，选自由卤素、烷基、烯基、炔基、芳基、醚、硫醚、羧酸、酯、酰胺、酰亚胺、碱金属或碱土金属磺酸盐、烷基磺酸酯、碱金属或碱土金属膦酸盐、烷基膦酸酯、胺和季铵组成的组；j’为零或为从1至4的整数，并且所述(t-PAES)聚合物具有范围从41000至90000的数均分子量(Mn)。
摘要（英）：

A poly(arylether sulfone) polymer [(t-PAES) polymer, herein after], wherein more than 70 % moles of the recurring units are recurring units (Rt) of formula (St): -E-Ar1-S02-[Ar2-(T-Ar3)n-SO2]m-Ar4- (formula St) wherein : n and m, equal to or different from each other, are independently zero or an integer of 1 to 5, each of Ar1, Ar2, Ar3 and Ar4 equal to or different from each other and at each occurrence, is an aromatic moiety, T is a bond or a divalent group optionally comprising one or more than one heteroatom; -E is of formula (Et), wherein each of R', equal to or different from each other, is selected from the group consisting of halogen, alkyl, alkenyl, alkynyl, aryl, ether, thioether, carboxylic acid, ester, amide, imide, alkali or alkaline earth metal sulfonate, alkyl sulfonate, alkali or alkaline earth metal phosphonate, alkyl phosphonate, amine and quaternary ammonium; j' is zero or is an integer from 1 to 4, and said (t-PAES) polymer having a number average molecular weight (Mn) ranging from 41 000 to 90 000.
