| titleOfInvention | Process for preparing a fluoroorganopolysiloxane |
| abstract | A process for preparing a fluoroorganopolysiloxane having a fluorine-containing organic group represented by the following formula: n n F--(--C.sub.g F.sub.2g O--).sub.d --C.sub.h F.sub.2h CH.sub.2 -- n n where d represents an integer of from 1 to 5, g represents an integer of from 1 to 3, and h is 1 or 2, comprising the steps of: n polymerizing a monomer comprising a fluorine-containing cyclotrisiloxane having the following formula (II): ##STR1## wherein R 1 represents the above fluorine-containing organic group, R 2 is a fluorine-free hydrocarbon group, and R 3 is a fluorine-free divalent hydrocarbon group, in the presence of an acidic catalyst or a basic catalyst, and in the presence of a water at a temperature of not higher than 80° C., and n neutralizing the resulting polymerization product. This process can produce the above polymer containing little low molecular weight compounds and having a desired polymerization degree in a good yield. |
