Abstract
A copolymer formed by reacting maleic anhydride or a maleimide or a mixture of these with an allylphenol, a methallylphenol, or substituted allyl or methallylphenol. The anhydride polymers are characterized as having a 1:1 molar ratio of maleic anhydride to phenol or substituted phenol. The maleic anhydride copolymers are water soluble materials, useful as epoxy resin modifiers and curatives, as ion exchange resins or membranes, laminates, and detergent additives and builders. The maleimide containing copolymers are also useful as epoxy resin modifiers and useful in the production of laminates, composites and coatings.
