聚芳醚腈合金的制备及性能研究

Preparation and Property Study of Polyarylene Ether Nitrile Alloys

将2类聚芳醚腈(PEN)共聚物PEN(HQ/RS)和PEN(HQ/PP),按不同质量比通过熔融共混制备PEN合金材料,测试其相容性、力学性能和热性能,发现聚合物合金在PEN(HQ/RS)质量分数分别为20%和80%时相容性良好,PEN(HQ/RS)的加入改善了PEN(HQ/PP)的加工性能,实验中不同质量比的合金均具有优良的力学性能和热性能。

Polyarylene ether nitrile （PEN） alloys were prepared by melt-blending two kinds of PEN copolymers PEN（HQ/RS） and PEN（HQ/PP） with different mass ratios. Their compatibility, mechanical properties and thermal properties were researched. It was found that the polymer alloys have good compatibility when PEN（HQ/RS） mass fractions are 20% and 80% respectively,and the blending PEN（HQ/RS） enhances the processability of PEN（HQ/PP）.AI1 the alloys with different mass ratios have good mechanical and thermal properties in experiment.
