Process for the preparation of powder coating composition |
摘要 |
A process for the preparation of a powder coating composition, wherein 5-90% by weight of at least one monomeric compound selected from glycidyl group-containing unsaturated compounds and methylglycidyl group-containing unsaturated compounds is copolymerized with 95-10% by weight of an ethylenically unsaturated monomer in methanol to obtain a resin solution. The resin solution is spray-dried to obtain a powdery resin. Alternatively, the resin solution is fed to an extruder having a die and a plurality of vent ports and extruded through the die, while removing volatile matters through the vent ports, to obtain extrudates. The extrudates are pulverized to obtain a powdery resin.
