Co-polymers of N-phenyl methacrylamide and glycidyl methacrylate of different compositions were synthesized by free radical solution co-polymerization of the monomers in dimethylformamide using benzoyl peroxide as the initiator at 70 • C. Solubility of the co-polymers was tested in various solvents. The molecular structure of the co-polymers was elucidated by infrared and proton nuclear magnetic resonance spectroscopy. The composition of the co-polymers was determined from their 1 H-NMR spectra by using the intensities of aliphatic and aromatic protons present in the co-polymer. The Finemann-Ross and Kelen-Tüdos models have been employed to determine the reactivity ratios of the monomers. The intrinsic viscosities of the co-polymers of GMA and PMA were determined using a Ubblehode viscometer. The thermal transitions of the co-polymers were determined using differential scanning calorimetry and thermogravimetric analysis.

“…Polymer supports [6] based on GMA are found to have versatile applications due to the presence of an oxirane group. The synthesis and characterization of co-polymers of glycidyl methacrylate with styrene has been reported by Sunderrajan et al [7]. The co-polymers of glycidyl methacrylate and styrene have been reported by Dhal [8].…”

“…T g GMA was found in literature to be equal to 76°C for M n ϭ 3100 g/mol. 24 According to the correction due to the difference of molar masses, T g GMA was calculated to be close to 87°C for M n ϭ 7500 g/mol. The modification of the GMA concentration in the acrylic copolymer from 5 to 20 mol % changed the average epoxy functionality of copolymer chains from about 2.4 to 9.8.…”

Acrylate-functionalized copolymers were synthesized by the modification of poly(butyl acrylate-coglycidyl methacrylate) (BA/GMA) and poly(butyl acrylateco-methyl methacrylate-co-glycidyl methacrylate).13 C-NMR analyses showed that no glycidyl methacrylate block longer than three monomer units was formed in the BA/ GMA copolymer if the glycidyl methacrylate concentration was kept below 20 mol %. We chemically modified the copolymers by reacting the epoxy group with acrylic acid to yield polymers with various glass-transition temperatures and functionalities. We studied the crosslinking reactions of these copolymers by differential scanning calorimetry to point out the effect of chain functionality on double-bond reactivity. Films formed from acrylic acrylate copolymer precursors were finally cured under ultraviolet radiation. Network heterogeneities such as pendant chains and highly crosslinked microgel-like regions greatly influenced the network structure and, therefore, its viscoelastic properties.

“…However, copolymerization reactivity ratios of S and GMA have to be known to be able to design, optimize, and control reactors for the production of such S/GMA copolymers. Up to now these reactivity ratios were determined only in bulk at 60 8C [4] and 65 8C [5] and in chlorobenzene [6,7] at 60 8C, that is, at temperatures much too low for our purposes.…”
