  • Radiation-curable acrylate-capped polycaprolactone compositions
    Patent number: RE29131
    Abstract: Unsaturated acrylate-capped polycaprolactone polyol derivatives are produced having terminal acrylyl groups and at least one polycaprolactone polyol chain residue in the molecule. In one of its simplest forms the final product can be the reaction product of a polycaprolactone diol an organic isocyanate and hydroxyethyl acrylate. These novel derivatives can be used to produce novel coating compositions that are readily cured to solid protective films.
