摘　　要：采用KH-570改性制备的可聚合有机化改性电气石与苯乙烯、乙酸乙烯酯进行共聚合反应制备了含电气石的功能聚合物,优化了其共聚反应条件。实验结果表明,当苯乙烯含量(体积分数)为20%、改性电气石的添加量为10 mg/mL时,功能聚合物的力学性能达到最佳,拉伸强度达到了3.34 MPa,弹性模量达到226MPa,功能聚合物的远红外辐射性能为0.95左右,其负离子释放性能随着改性电气石添加量的增加呈近似线性上升趋势,展示了优良的力学性能和远红外辐射及负离子释放功能,且可以纺丝制备含电气石的功能纤维。The tourmaline-containing functional copolymer is synthesized via copolymerization of styrene,vinyl acetate and polymerisable organic tourmaline modified with KH-570,and the copolymerized conditions are optimized.The experimental results show that the mechanical performances of the tourmaline-containing functional copolymer are optimums while the volume fraction of styrene is 20%and the dosage of modified tourmaline is 10 mg/mL,its tensile strength attains 3.34 MPa,modulus of elasticity reaches to 226 MPa,the far infrared emissivity of functional copolymer is about 0.95,and its negative ion release quantity trends to linear increase with the dosage increasing of modified tourmaline.It exhibits an excellent mechanical performances and negative ion release,far infrared radiation performances,and the tourmaline-containing functional fibre could be fabricated by means of wet spinning.
