Title: Manufacturing method of silicone emulsion containing small amount of residual siloxane oligomer
Inventor: WROLSON BURT MICHAEL
IPC: C08G77/32
Filed: 2002-02-06
Abstract: PROBLEM TO BE SOLVED: To provide a method for removing a residual volatile siloxane oligomer from an emulsion containing a siloxane polymer prepared by suspension polymerization of a volatile siloxane oligomer. SOLUTION: A mixture of a volatile siloxane oligomer, a surfactant, water and a polymerization catalyst is subjected to suspension polymerization by heating. Subsequently, the suspension polymerization catalyst is neutralized and steam stripping is effected until the content of the volatile siloxane oligomer is decreased to less than 0.18 pt.wt. relative to the unit weight of the siloxane polymer in the emulsion. The stripped emulsion is cooled and another catalyst is added thereto to continue polymerization further. Then, the catalyst is neutralized to give an emulsion which contains a siloxane polymer having a higher molecular weight than that of the siloxane polymer initially prepared and has a volatile siloxane oligomer content of less thin 0.18 pt.wt.
