OLIGOMERS

        In photochemistry, oligomers are reactive low molecular weight resins in between monomers and polymers.  They are usually liquid at room temperature and are principally used to formulate liquid photoplymer compositions and radiation-curable adhesives, coatings and inks.  Examples include epoxy acrylates, urethane acrylates, polyester acrylates, acrylated acrylics, epoxy resins, cycloaliphatic epoxides, silicones, unsaturated polyesters etc.  Acrylates also include derivatives of methacrylic acid.
