Title:
PROCESS FOR PRODUCING AQUEOUS DISPERSION
Document Type and Number:
WIPO Patent Application WO/2004/067579
Kind Code:
A1
Abstract:
One or more (meth)acrylates having a polyfluoroalkyl group and a non-fluorinated polymerizable monomer are emulsified in the presence of a surfactant and a polypropylene glycol compound having a molecular weight of 250 to 5,000. The monomers are then copolymerized in the presence of a polymerization initiator to produce an aqueous dispersion. Even when the copolymer is one formed from (meth)acrylates having, as polyfluoroalkyl groups, two or more kinds of perfluoroalkyl groups including a C12 or higher perfluoroalkyl group, the aqueous dispersion prepared has excellent emulsion stability. The aqueous dispersion can hence be effectively used as a water-and-oil repellant, etc.
