Thio-Bromo 'Click,' Post-Polymerization Strategy for Functionalizing Ring Opening Metathesis Polymerization (ROMP)-Derived Materials

摘要

The use of a thio-bromo click strategy as an efficient postpolymerization tool is described. Norbornene derivatives bearing an alpha-bromo ester could be polymerized using Grubbs 2nd generation initiator to provide alpha-bromo ester-containing homo-and block copolymers that could be efficiently functionalized through reactions with various thiols. A one-pot strategy was also used, in which up to four different thiols were reacted simultaneously. This chemistry could also be used as an efficient cross-linking strategy to form ROMP-based gels as well as a tool for terminal functionalization of polypropylene-based oligomers.
