酚红型聚碳酸酯的合成及性能研究
Study on Synthesis and Properties of Phenol Red Polycarbonate
摘要
Abstract
Phenol red(PR)and triphosgene(BTC)were used as raw materials to synthesize phenol red-based polycarbonate(PR-PC)via interfacial polycondensation.The intrinsic viscosity molecular weight of the product was measured,and the structure of the product was verified by infrared absorption spectroscopy.The effects of PR on the properties of PC were also investigated.The results show that PR-PC has a glass transition temperature of 247℃,a 5%weight loss temperature of 477℃,a heat deflection temperature of 179℃,and a Vicat softening temperature of 198℃,all of which are significantly higher than those of conventional bisphenol A-based polycarbonate(BPA-PC).The oxygen index of PR-PC is 35.8%,and it achieves a V-0 rating in the vertical burning test and passes the needle flame test,indicating a significant improvement in flame retardancy.The mechanical properties of PR-PC are also enhanced.However,the optical properties of PR-PC are somewhat reduced,making it unsuitable for applications requiring high color and transparency.Polycarbonates with different thermal and flame retardant properties can be obtained by copolymerizing PR,bisphenol A,and BTC at different molar ratios.关键词
