Abstract
Process for the preparation of latices by batchwise radical polymerization of one or more monomers, comprising the participation, in the polymerization, of: (a) one or more fine dispersions of one or more finely dispersed monomers and (b) one or more seed latices of one or more seeding polymers.
Claims23
A process for the preparation of latices by seeded batchwise radical microsuspension polymerization of one or more monomers, comprising polymerizing:
- (a) one or more fine dispersions comprising one or more finely dispersed monomers, at least one of said fine dispersions comprising one or more oil-soluble initiators, and
- (b) one or more seed latices comprising one or more seeding polymers.
The process as claimed in 1, wherein said one or more fine dispersions is/are prepared by a high-pressure homogenizer.
