摘要

通过加入第三单体4

4′-二（2-甲基苯氧基）二苯砜与1

4-二苯氧基苯（DPB）和对苯二甲酰氯（TPC）进行三元无规共聚

合成了一系列分子主链带砜基和主链芳环上含甲基侧基的聚（芳醚砜醚酮酮-co-醚醚酮酮）共聚物

并用FT-IR、DSC、WAXD和TG对其进行了表征.结果表明

共聚物的玻璃化转变温度随着第三单体摩尔含量的增加而逐渐升高

熔融温度则逐渐降低

当其摩尔含量为10%

0%时

共聚物具有优良的耐热性能及耐溶剂、耐酸碱性能.

Abstract

Poly（aryl ether ether ketone ketone）s as outstanding polymer have excellent thermal stability

resistance to creep and so on.But their high melting points and low solubility in common organic solvents limited their applications.One of the modifications is introducing novel monomer to backbone.In this paper

a series of high molecular weight poly（aryl ether sulfone ethe retone ketoneco-ary ether ketone）s containing mono-ortho-methyls were obtained by low temperature solution polycondensation

taking 4

4′-bis（2-methylphenoxy）diphenylsulfone（o-MeDPODPS）as the third monomer

which aimed to introduce methyl pendant into the main chain to decrease melting temperature.The resulting copolymers’ η

inh

was in the range of 0.75～1.36 dL/g

and they were characterized by FT-IR

WAXD

DSC results and TG.The DSC results revealed that the glass transition temperature of the copolymers increased with increasing the molar ratio of o-MeDPODPS

while their melting points and crystallinity decreased.The same phenomenon occurred in the 5% weight loss temperatures of the copolymers

which could be attributed to the decomposability of methyl pendant.They also show good resistance to common organic solvents in the solubility test.When the molar ratio of o-MeDPODPS is 30%

the T

of the copolymer is 9℃ higher in comparison to PEEKK

while the T

is 44℃ lower.
