Glycidyl methacrylate and N‐vinyl‐2‐pyrrolidone copolymers: Synthesis, characterization, and reactivity ratios

Abstract

AbstractFree radical copolymerization of glycidyl methacrylate (GMA) and N‐vinyl‐2‐pyrrolidone (VPD) was carried out using 2,2′‐azobisisobutyronitrile (AIBN), in chloroform at 60°C. The polymers were characterized by IR and 13C‐NMR spectroscopic methods. The percentage composition of the copolymers were established by microelemental analysis and by 13C‐NMR spectroscopy. The copolymerization reactivity ratios were computed using the Fineman‐Ross method, the Kelen‐Tudos method, and the extended Kelen‐Tudos method. The molecular weights of the copolymers were obtained by GPC measurements. Thermal properties of the homo‐ and copolymers were also studied by thermogravimetric analysis. The copolymers were tested as adhesives for leather‐to‐leather and leather‐torubber bonding.
