Silicone oil is a polyorganosiloxane of different degree of polymerization chain structure. It is obtained by hydrolysis of dimethyldichlorosilane with water to obtain a polycondensation ring, and the ring body is obtained by cracking and rectifying to obtain a low ring body, and then the ring body, the heading agent and the catalyst are put together to be condensed to obtain each. A mixture of different degrees of polymerization can be obtained by removing low boilers by distillation under reduced pressure.
