Abstract:
A process for preparing an aqueous monomer/alkyd emulsion which comprises:mixing at least one alkyd resin having at least two carbon-carbon double bonds, and optionally at least one cosurfactant, in at least one ethylenically unsaturated monomer or mixture thereof, thereby forming an alkyd-resin-in-monomer solution, and combining the alkyd-resin-in-monomer solution with water, and at least one surfactant, and agitating the resulting mixture under high shear; thereby obtaining an aqueous monomer emulsion comprising: an aqueous continuous phase; and an organic disperse phase; the organic disperse phase comprising: said at least one ethylenically unsaturated monomer or mixture thereof, said at least one alkyd resin and optionally said at least one cosurfactant, provided that said at least one cosurfactant is present when the amount of alkyd resin is less than 30 parts by weight based on 100 parts by weight of monomer; and said organic disperse phase being in the form of droplets having an average droplet diameter range from about 10 to about 1,000 nanometers.
