    • Coating compositions containing aqueous dispersion of higher molecular weight epoxy resin are produced by advancing the molecular weight of an aqueous dispersion of a low molecular weight epoxy resin having a number average molecular weight between about 360 and 2,000. The water dispersed low molecular weight epoxy resins are advanced in molecular weight by coreaction with diphenol at temperatures above about 105.degree. C. and at pressures above about 5 psig to produce the aqueous dispersed high molecular weight epoxy resin. The aqueous dispersed high molecular weight epoxy resin can be further copolymerized with ethylenic monomers, if desired, to produce an acrylic epoxy emulsion binder useful protective coatings.
    • 含有较高分子量环氧树脂的水性分散体的涂料组合物是通过使数均分子量在约360和2,000之间的低分子量环氧树脂的水性分散体的分子量提高而得到的。 水分散的低分子量环氧树脂通过在高于约105℃的温度和高于约5psig的压力下与二酚共核化而分子量提高以产生水分散的高分子量环氧树脂。 如果需要,水性分散的高分子量环氧树脂可以进一步与烯属单体共聚,以生产丙烯酸环氧乳液粘合剂有用的保护涂层。
