PREPARATION OF UV-CURABLE URETHANE COMPOSITIONS |
摘要 |
A method of preparing UV-curable urethane compositions is disclosed. The method comprises two steps. First, isophorone diisocyanate (IPDI) reacts with a hydroxy-functional resin to form an NCO prepolymer. Second, the NCO prepolymer reacts with a hydroxy-functional ethylenic monomer to form the UV-curable urethane composition. The hydroxy-functional resin comprises at least about 2 wt % of recurring units of a propoxylated allylic alcohol. The method of the invention allows the preparation of UV-curable urethane compositions from acrylic polyols without gel.
