Abstract: Aqueous compositions suitable for sanitary can coatings comprising the neutralized water dispersible ionic polymer product of the reaction of an epoxy resin with acid polymer, and a different resin which is not necessarily self-dispersible in water, as well as several methods of preparing such compositions, are disclosed. The second resin which is not necessarily self-dispersible in water is introduced either preformed at any stage or is prepared, in situ, in the presence of the epoxy resin esterified with acid polymer either before the ionic epoxy resin-acid polymer product is dispersed in water. The epoxy resin-acid polymer product acts as a polymeric surfactant capable of keeping even a normally non self-dispersible second polymer in stable dispersion in water.

Abstract: Novel compositions are provided which comprise a polyphenylene ether, optionally a high impact polystyrene, optionally, an effective amount of an aromatic phosphate flame retardant, and a low molecular weight polymer selected from a polyolefin glycol or a polyamide, said composition being free from or excluding a substantial content of polyolefin, such as polyethylene. Such compositions when molded are readily paintable, and exhibit good adhesion between the paint and the molded compositions as distinguished from compositions containing polyolefins, such as polyethylene, which has been found to adversely affect paint adhesion.

Included within the disclosure of the invention are methods of preparing and molding such compositions and the molded products obtained therefrom.
