Patent number: 5869727Abstract: Disclosed is an improved process for the manufacture of silicone containing copolymers via a hydrosilation reaction, in which the catalyzed reaction of organohydrosiloxane and olefinic polyether is carried out at between 20.degree.-120.degree. C., preferably 70.degree.-120.degree. C., under a vacuum between 750-1 mmHg. The reaction under these conditions results in a copolymer of a higher quality as compared to copolymers made by the traditional method without the benefit of a vacuum. If desired, the reaction can be taken to its clear point in a volatile compatibilizing solvent (for example toluene, xylene, or isopropyl alcohol), this solvent can then be removed from the reaction system, and another less volatile solvent, such as dipropylene glycol or polypropylene glycol, may then be added.Type: GrantFiled: August 8, 1997Date of Patent: February 9, 1999Assignee: OSi Specialties, Inc.Inventors: William E.
