Popis: 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.
