I'm not sure if your looking for an -OH in the polymer or just in the mix. Many multifunctional polyols are used for epoxies and urethane synthesis/crosslinking. For acrylate(free-radical) chemistry you can find products from Sartomer with free -OH functionality . You can also use Darocur 1173 and/or Irgacure 184 from Ciba as photoinitiators, but these do not become part of the matrix.
