Silicone oil is obtained by hydrolysis of dimethyldichlorosilane, and then converted into initial polycondensation rings. After the process of cleavage and correction, the lower ring body is obtained. By combining ring bodies with capping agents and telomerization catalysts, we created mixtures with different degrees of polymerization. Finally, the low boilers are removed by vacuum distillation to obtain highly refined silicone oil.
