| Abstract: | To obtain a new kind of resin for practical UV curable powder coating systems, hyperbranched polyester, Boltorn TM H20, was modified with octadecyl isocyanate (or palmitoyl chloride) and acryloyl chloride, thus resulting in an UV curable resins with crystalline molecular shell and amorphous interior. The high melting point( T m) can be resulted largely by the crystalline area of the crystallizable moieties. The degree of crystallinity is higher with more crystallizable moieties. As a result, T m of the resin modified with octadecyl isocyanate is higher than that of one modified with palmitoyl chloride. The hyperbranched polyester Boltorn TM H20 modified with octadecyl isocyanate maybe used for powder coating systems. |
