RADICAL COPOLYMERIZATION OF ACRYLOYLMORPHOLINE WITH 2- HYDROXYETHYL METHACRYLATE: MONOMER REACTIVITY RATIOS AND THERMAL PROPERTIES

34476

Poly(acryloylmorpholine-co-2-hydroxyethyl methacrylate) were prepared by traditional free radical polymerization. Copolymerization with acryloylmorpholine (ACM) and 2-hydroxyethyl methacrylate (HEMA) monomers were carried out in tetrahydrofuran solution at 60°C using 2,2 -azobisisobutyronitrile (AIBN) as initiator. The copolymers were characterized by FT-IR, 1H and 13C nuclear magnetic resonance (NMR). Monomer compositions of the copolymers were established by nitrogen results of elemental analysis. The reactivity ratios of monomers ACM (r1) and HEMA (r2) in the copolymer were calculated by various methods. According to these methods, r1 was 1.73-2.01 and r2 was 0.48-0.74. Thermogravimetric analysis was used to investigate the thermal properties of copolymers.
