Abstract
Radiation-curable low molecular weight partial ester copolymer compositions comprising products of a terminally ethylenically unsaturated compound and a maleic anhydride characterized by having free-anhydride functionality are provided. The partial esters are produced by esterification of certain copolymers under anhydrous conditions with a hydroxyalkyl acrylyl compound, or an admixture thereof with a monohydric alcohol. The compositions of the invention are useful as radiation cross-linkable diluents for radiation-hardenable compositions, particularly in improving adhesion promotion and/or dispersive capabilities of binder resins.
