Graft copolymer coating compositions

摘要

Graft copolymers containing: (1) a phenolic resin; and (2) a poly(alkylene oxide) chain pendant to the phenolic resin, selected such that the graft copolymer has a solubility of no more than about 10 g/L in water, are taught. The graft copolymers are useful in coatings compositions with a curing agent, a solvent, and optionally an epoxy resin. The curable compositions have improved flexibility and/or solvent resistance. They are particularly useful in can coatings.
