Abstract Investigations on free radical copolymerization of 1-vinyl naphthalene (1-VNph, monomerM 2) with styrene (St), methyl methacrylate (MMA) and acrylonitrile (AN) (monomersm 1) in bulk at 60°C with AIBN as initiator are presented. Relative reactivity ratios were calculated by the Kelen-Tüdös method yielding:r st=0.70 ±0.23 andr 1−VNph=2.02 ±0.40 for system St/1-VNph;r MMA=0.32 ±0.10 andr 1−VNph=0.57 ±0.07 for system MMA/1-VNph andr AN=0.11 ±0.03 andr 1−VNph=0.45 ±0.09 for system AN/1-VNph.Q, e values for 1-VNph according to Alfrey, Price scheme were calculated toQ 1−VNph=1.02,e 1−VNph=−0.62.
