- Dual-reactive hyperbranched polymer synthesis through proton transfer polymerization of thiol and epoxide groups
-
A new synthesis of hyperbranched polymers through proton transfer polymerization of thiol and epoxide groups is presented. For this, an AB 2 monomer bearing two epoxides and a thiol groups is synthesized. Base-catalyzed proton transfer polymerization of this monomer led to the formation of a polythioether-based hyperbranched polymer with a 65-69% degree of branching and carrying about 2% of disulfide-based structural defects. This polymer contained two reactive sites, a hydroxyl group and an epoxide unit, distributed throughout the branched scaffold. The epoxide groups could be employed in anchoring an alkyl, aryl, or ethylene oxide chain through a thiol-epoxy reaction, while the hydroxyl groups produced during the polymerization and the first functionalization reactions could be engaged in attaching positively charged primary ammonium groups to the branched backbone. These sequential postpolymerization modifications transformed the general dual-reactive scaffold into dual-functionalized hyperbranched materials with potential utility in the arena of gene delivery applications.

- ISOCYANURATE EPOXY COMPOUND HAVING ALKOXYSILYL GROUP, METHOD OF PREPARING SAME, COMPOSITION INCLUDING SAME, CURED PRODUCT OF THE COMPOSITION, AND USE OF THE COMPOSITION
-
The present invention relates to an alkoxysilyl-based isocyanurate epoxy compound, a method of preparing same, a composition including same, a cured product of the composition and a use of the composition. A complex including the compound illustrates good heat resistance, particularly, a low coefficient of thermal expansion (CTE), and a high glass transition temperature or Tg. A cured product of the composition illustrates flame retardancy and does not use a separate silane coupling agent. According to the present invention, an isocyanurate epoxy compound including an alkoxysilyl group and an epoxy group at a core; a method of preparing the epoxy compound prepared by epoxidation and alkoxysilylation of a starting material; an epoxy composition including the epoxy compound; and a cured product of the epoxy composition and a use of the epoxy composition, are provided. In the complex of the composition including the novel alkoxysilyl-based isocyanurate epoxy compound according to the present invention, chemical bonding efficiency may be improved when making a chemical bond between the alkoxysilyl group in the epoxy compound and a filler and when forming an epoxy complex through a chemical bond between alkoxysilyl groups in the epoxy compound having the alkoxysilyl group. Therefore, good heat resistance, that is, a low CTE and a high glass transition temperature or Tg may be shown. In addition, the cured product of the composition including the epoxy compound according to the present invention may show good flame retardancy.
