Abstract

Different functional group/moiety containing methac rylate copolymers are synthesized via free radical solution polymerization in N,N-dimethylformamide at 70 °C u sing 2,2-azo-bisisobutyronitrile (AIBN) as initiato r. The monomers and copolymers are characterized by spectr oscopic techniques. The compositions of the copolym ers were determined by using UV spectroscopy. The reactivity ratios of the monomers were obtained from linear m ethods. Using these linear methods, average r 1 = 0.9 and r 2 = 1.09 were obtained. The mean sequence length is d etermined by statistical method using average values of r 1 and r 2 . Thermal characteristics of the homo and copolymer s of NPEMA with PAPMA were evaluated by using thermograv imetric analysis (TGA). The thermal degradation kin etic parameters of homo and copolymers of NPEMA with PAP MAare quantitatively evaluated using namely Broido method. The antimicrobial screening of homo and cop olymers of NPEMA with PAPMA is determined by quantitative method.
