有机硅聚合物中二甲基硅氧烷环体含量分析进展

Progress in the Content Analysis of Dimethylsiloxane Rings in Organosilicone Polymers

有机硅聚合物的制备大多是以二甲基硅氧烷环体为原料,经开环聚合和平衡反应等制得,其中,二甲基硅氧烷的四、五和六环体会存在于产品中。近年来,随着国内外对二甲基硅氧烷环体生理毒性研究的不断深入,人们对有机硅聚合物制品中二甲基硅氧烷环体的含量越来越关注,相关分析方法和手段也较多,获得了很好的结果。本文针对近十年来二甲基硅氧烷环体国内外分析方法的研究现状和发展趋势进行了较为系统的比较和阐述,以期为有机硅聚合物产业的研发提供技术支持。

Most organosilicon polymers are prepared by ring opening polymerization and equilibrium reaction with dimethylsiloxane as raw material.The four,five and six rings of dimethylsiloxane exist in the products.In recent years,with the deepening of the research on the physiological toxicity of dimethylsiloxane ring at home and abroad,people pay more and more attention to the content of dimethylsiloxane ring in silicone polymer products,and there are many related analysis methods and means,and good results have been obtained.In this paper,the research status and development trend of dimethylsiloxane cyclones at home and abroad in recent ten years were systematically compared and elaborated,in order to provide technical support for the research and development of silicone polymer industry.
