Synthesis of Four-Armed Star-Shaped Poly(N,N- Diethylacrylamide) by Group Transfer Polymerization in the Presence of Hydrosilylane

Abstract:

The core-first synthesis of four-armed star-shaped poly(N,N-diethylacrylamide) with predicted molecular weights and narrow molecular weight distributions (Mw/Mn=1.17) was carried out by the Tris(pentafluorophenyl)borane (B(C₆F₅)₃) -catalyzed group transfer polymerization (GTP) using ethyldimethylsilane (EtMe₂SiH) as hydrosilylane. The optimal ratio of the precursor to the hydrosilylation agent was 1:4.2.
