| Abstract | ||||
| IN the present study novel acrylate polymers were prepared from … different feed compositions of ethyl acrylate (EA), methyl methacrylate (MMA), styrene (St) and N-(benzothiazole-2-yl) maleimide (BTM) monomer via emulsion polymerization technique using sodium lauryl sulfate as a surfactant and ammonium persulfate as an initiator. The chemical structure of BTM monomer was confirmed by elemental analysis in addition to FT-IR, 1H-NMR and mass spectroscopy. The prepared acrylate polymers of different compositions were also investigated by FT-IR, GPC, TGA and DSC. The solubility of both BTM monomer and the formed polymers of different compositions in various solvents was also investigated. The obtained results showed that the thermal decomposition of the prepared polymers which has taken place occurred in a single step in the temperature range from 345 to 436°C. The mechanism of the thermal degradation of the prepared polymers was confirmed via kinetic analysis of their thermal degradation using Broido, Coats-Redfern and Horowitz-Metzger methods. | ||||
