PROCESS FOR PREPARING A FILM-FORMING MATERIAL

摘要

A process for preparing a film-forming material by reacting at least two .alpha., .beta.-ethylenically unsaturated monomers one of which is acrylonitrile with a drying or semi-drying oil-modified alkyd resin comprising 1% - 4% itaconic acid and then cooling the reaction mixture rapidly such that a dispersion of polymer particles of maximum diameter 2 micron is formed. the film-forming materials thus prepared are useful as constituents of fast-drying automotive refinish enamels.
