Abstract

Copolymer of 3-(trimethoxysilyl) propyl methacrylate (TMSPM) with N-vinyl pyrrolidone (VP) was synthesized by free radical polymerization in dry benzene using (BPO) as initiator. The copolymer was characterized by FTIR, 1H-NMR. Thermal properties of homopolymers and copolymers were studied by TGA and DSC. The copolymer composition was determined by elemental analysis. The monomer reactivity ratios were estimated by different procedures: Fineman-Ross, Kelen-Tudos, Mayo-Lewis and curve fitting method. The derived reactivity ratios (r1, r2) are: (3.722, 0.097), and found that the reactivity of the monomer TMSPM is more than the monomer NVP. The sequence distribution of monomers in the copolymer and the microstructure of copolymer were calculated by statistical method based on the average reactivity ratios.
