摘要
探讨了采用Me2SiCl2水解物为原料经碱催化平衡反应制备α,ω-二羟基聚二甲基硅氧烷时产物黏度的影响因素,主要包括水解物、氢氧化钾、降解用水、反应温度、氮气等.并基于长期的生产实践经验对上述反应中产物黏度无法达到预期目标或聚合时长超出均值时可采用的排查方法进行了梳理总结.
Abstract
α,ω-dihydroxypolydimethylsiloxane was prepared with Me2SiCl2 hydrolysate as raw material by alkaline catalytic equilibrium reaction.The factors on the viscosity of dihydroxypoly dimethylsiloxane were discussed,which was including hydroly-sate,potassium hydroxide,degradation water,temperature and nitrogen gas.Based on the practical experience,the solutions are summarized when the viscosity of the products cannot go as expected or the polymerization time exceeds.
