ABSTRACT:
The invention relates to a novel method of preparing aqueous polymeric colloids comprising the steps of (a) polymerization in organic solvent at high concentration of the monomers (b) emulsification of the resultant polymer solution in water using small proportion of surfactant. The pH of the resulting emulsion is adjusted to 6.5 to 10 with amines. The structure of the polymers in the present invention is highly hydrophobic so that, even at full neutralization of the carboxylic acid groups with amines, it would not produce an aqueous solution. Furthermore, in the absence of surfactant, a stable colloidal emulsion cannot be attained.
The aqueous coating composition has satisfactory performance as interior and/or exterior coating for food, beer, beverage and other metal containers. The emulsions can be easily applied by spraying or direct roller coating and baked to give films of outstanding properties.
