摘　　要：采用4,4’-二氯苯砜、4,4’-二氟二苯甲酮等为原料,通过两步法制备得到不同酮基含量的聚芳硫醚砜/酮聚合物(K-PASS)。采用红外光谱、X射线光电子能谱、搭接剪切性能等测试对聚合物的制备以及聚合物与钛合金的搭接剪切强度进行了研究。结果表明,通过常压法成功制备了不同酮基含量的K-PASS,K-PASS与钛合金的搭接剪切强度随着酮基含量的增加呈现先增大后减小的趋势,当酮基含量为50%时,搭接剪切强度达到最大值,为12.6MPa,相较于PASS纯树脂与钛合金的剪切强度提高了34.5%。Using 4,4′-dichlorophenyl sulfone(DCDPS),4,4′-difluorobenzophenone(DFBP),etc.as raw material,polyarylene sulfide sulfone/ketone copolymers(K-PASS)with different copolymerization ratios were synthesized through a two-step method.The performance of the polymers and the lap shear strength of the polymers with the titanium alloy were studied through infrared spectroscopy,X-ray photoelectron energy spectrum,lap shear performance,etc.The results show that K-PASS with different ketone carbonyl contents was successfully synthesized by atmospheric pressure reaction.The lap shear strength of K-PASS and titanium alloy is increased first and then decreased with the increase of carbonyl group content.When the ketone carbonyl ratio reaches 50%,the lap shear strength achieves the maximum value of 12.6 MPa,which is 34.5% higher than that of pure PASS with titanium alloy.
