Abstract
(EN)
A hybrid alkyd acrylic latex and a process for its preparation are taught. The process comprises forming an oil phase comprising an alkyd, a drier, and at least one ethylenically unsaturated monomer, wherein the oil phase solubilizes the drier; combining the oil phase with an aqueous phase, wherein the aqueous phase comprises a surfactant, to form a pre-emulsion; homogenizing the pre-emulsion thereby forming a miniemulsion, wherein the drier is solubilized in the oil phase; initiating the polymerization by adding a free radical initiator, thereby polymerizing the at least one ethylenically unsaturated monomer in the miniemulsion and forming a latex polymer emulsion having latex polymer particle sizes in the range of 40 nm to 700 nm.
