Synthesis and characterization of new copolymers from glycidyl methacrylate and tetrahydrofurfuryl acrylate: determination of reactivity ratios
The new copolymers from different feed compositions of glycidyl methacrylate (GMA) and tetrahydrofurfuryl acrylate (THFA) were synthesized using free radical polymerization in toluene at 70±1 °C using benzoyl peroxide (BPO) as initiator. The polymers were characterized by 1H NMR, 13C NMR and FTIR...
