Abstract
Atom Transfer Radical Polymerization (ATRP) has proven to be a powerful technique to obtain polymers with narrow polydispersities and controlled molecular weight. It also offers control over chain-ends. N-allyl-2-bromopropinamide (ABPN) was synthesized by one step reaction which involved on amidification of 2-bromo-propionyl bromide with allyl amine. 1H NMR has confirmed the structure of the ABPN. The well-defined polystyrene was synthesized by using ABPN as initiator in ATRP method. The results of the polymerization were significantly affected by reaction conditions. The vinyl end-functional polystyrene obtained was characterized by Gel Permeation Chromatography (GPC) and NMR analysis.
Highlights
The development of Living Radical Polymerization (LRP) techniques constitutes one of the key developments in the field of synthetic polymer chemistry, allowing for the synthesis of a variety of polymers with molecular weight distributions and well defined architectures, with precise control over the compositions and structures (Wang and Matyjaszewski, 1995a; 1995b; Kato et al, 1995; Kotani et al, 1996; Matyjaszewski et al, 1997a)
The yield increased with time and showed linear relationship. These results suggest that the living polymerization of styrene proceeded at 115°C by ABPN/CuBr/BiPy catalyst system with slow initiation
The initiator ABPN was synthesized in a good yield
Summary
The development of Living Radical Polymerization (LRP) techniques constitutes one of the key developments in the field of synthetic polymer chemistry, allowing for the synthesis of a variety of polymers with molecular weight distributions and well defined architectures, with precise control over the compositions and structures (Wang and Matyjaszewski, 1995a; 1995b; Kato et al, 1995; Kotani et al, 1996; Matyjaszewski et al, 1997a). Synthesis of well defined reactive end-functional polymers has great importance for their use as macromonomer, macroinitiator, precursor for block copolymers etc.
