EMULSION COMPOSITION FOR BAKING TYPE PAINT

摘要

PURPOSE:To improve water resisting property and weatherability of an emulsion compsn. for paint resulting from the emulsion polymerization of monomer mixt. of specified acrylamides and radical polymerizable ethylenic ally unsatd. monomers. CONSTITUTION:Monomer mixt. consisting of (a) from about 2-40% by weight of at least one acrylamide such as N-methylolacrylamide and N-alkoxymethyl-acrylamide such as N-methoxymethylacrylamide, N-ethoxy-methylacrylamide, (b) from about 1-25% of radical polymerizable ethylenic ally unsatd. monomer contg. hydroxyl group and having the formula (wherein R1 and R2 are H or CH3 and n is 1-15) and (c) from about 97-35% of radical polymerizable ethylenically unsatd. monomer (e.g. styrene, acrylic acid, etc.) other than the above (a) and (b), is dispersed in water. The emulsion polymerization is carried out by the irradiation of ionization radiation to produce the desired composition.
