Radical-initiated copolymerization of Cinnamyl methacrylate (CMA) and Ethyl methacrylate (EMA) monomers were carried out at lower conversions (<10%) using 2,2’-azobisisobutyronitrile (AIBN) as initiator, in 1,4-dioxane at 60 °C and nitrogen atmosphere. Structure and composition of copolymers for wide range of monomer feed were determined by Fourier Transform Infrared (FTIR) and Ultra-violet (UV) spectroscopy analysis through recorded of analytical absorption bands for monomers units. Monomer reactivity for CMA (1)–EMA (2) pair were determined by the Finneman-Ross (F-R) and Kelen- Tudos (K-T) methods. They are r1= 0.135 and r2= 0.868 as determined by K-T method. Parameters Q1, e1 of CMA monomer were calculated according to Alfrey-Price model. A relatively high activity of EMA was observed as compared to CMA growing radical. This result can be explained by sterical hindrance caused by chemical structure of cinnamyl pendant group in chain growth reactions.
The soil from an industrial area in Algeria was contaminated with Cr (8370 mg kg−1), Ni (1135 mg kg−1) and zinc (1200 mg kg−1).
