  • Patent number: 6541537
    Abstract: A compound and a method of forming a photopolymerizable acrylated glycidyl acrylic terpolymer resin compound is disclosed. The polymeric resin may be formed in a two-step process. A photopolymerizable acrylic hybrid polymer is suitable for forming films having glass transition temperatures from about −55 degrees C. to about 110 degrees C. A non-aromatic photopolymerizable acrylate polymer may be formed by combining, in a first step, a reactive source of epoxide ion groups. In a second step, the glycidyl acrylic terpolymer formed in the first step is reacted with a catalyst and a source of unsaturated acid or anhydride to form an acrylate polymer. A ring opening reaction is employed such that an acid or an anhydride containing a conjugated double bond forms an acrylated acrylic, an acrylated fluorinated acrylic, an acrylated silonted acrylic, or an acrylated halogenated grafted acrylic. The cure process is initiated with specific UV or visible light promotors and/or with a UV or visible light source.
