“…The copolymer composition and its distribution depend on monomer reactivity ratios. The most common mathematical model of copolymerization is based on finding the relationship between the composition of copolymers and the composition of the monomer feed in which the monomer-reactivity ratios are the parameters to be determined (24,25). The calculation of the monomer -reactivity ratios requires the mathematical treatment of experimental data on the composition of copolymers and monomer in feed mixtures.…”

A new methacrylate monomer 2-(4-nitrophenyl)-2-oxoethyl-2-methacrylate (NFM) was synthesized and its radical copolymerization with glycidyl methacrylate (GMA) was studied in 1,4-dioxane solution at 65 C using 2,2 0 -azobisisobutyronitrile as an initiator. The synthesized monomer and copolymers were characterized by FTIR, 1 H and 13 C-NMR spectroscopy. The analysis of reactivity ratios revealed that NFM is less reactive than GMA, and copolymers formed are statistically in nature. Thermogravimetric analysis of the polymers reveals that the thermal stability of the copolymers increases with an increasing in the mole fraction of NFM in the copolymers. Glass transition temperatures of the copolymers decreased with an increasing of NFM molar fraction in copolymers. In addition, according to the results obtained from the contact angle and zeta potential measurements the hydrophobic character of the polymer decreases (it means surface free energy increases) and its zeta potential becomes more negative with increase of NFM ratio in the copolymer. Polymers with carbonyl functional groups have been particularly interesting because of their use as photoresists.

The free radical copolymerization of nadic anhydride (NA) and styrene (St) at 80°C has been investigated for the first time. The copolymerization was done in toluene using benzoyl peroxide as initiator. The monomer reactivity ratios were calculated from the copolymer composition (estimated from the acid value) by using Fineman–Ross, Kelen–Tüdös, and Extended Kelen–Tüdös methods. The reactivity ratios (rNA, = 0.34, rST = 0.84) implied a good copolymerizability for the monomer pair and existence of an azeotropic composition at fNA = 0.195. The unsaturation in nadic anhydride exhibited good copolymerizability despite the fact that the double bond is isolated and allylic in nature. The usual retardation by the allylic protons was not significantly felt in this case, as the allylic protons were located at a bridge head posing geometric restrictions for stabilization of the allylic free radicals. However, an increase in concentration of NA in the feed decreased the overall rate of copolymerization. Based on the reactivity ratio, the probability for formation of sequences of NA in its copolymer with styrene was computed for a few compositions.

“…Copolymers vary in physical properties from homopolymers, and their magnitude depends on the copolymer structure. Changing the monomer form and amounts, which join the copolymer, gives the chance to manufacture almost infinite quantities of different polymers 5–7 . Monomer reactivity ratios are important quantitative values for predicting copolymer type and understanding the kinetic aspects of copolymerization.…”

In the first step of this study, 2‐[(methoxy‐1,3‐benzothiazole‐2‐yl)amino]‐2‐oxoethyl methacrylate (MBAOM) monomer was synthesized and characterized. Then, a series copolymers were obtained by free‐radical copolymerization method of MBAOM and glycidyl methacrylate, which is a commercial monomer at 65°C in 1,4‐dioxane solvent. Structural characterizations of synthesized monomer and copolymers were carried out using Fourier transform infrared spectrophotometer and nuclear magnetic resonance spectroscopy (1H and 13C‐NMR) instruments. The composition of the copolymers was estimated by elemental analysis. The thermal behaviors of all the polymers have been investigated using the differential scanning calorimetry and the thermogravimetric analysis. A kinetic study of the thermal decomposition of copolymers was investigated using thermogravimetric analyzer with non‐isothermal methods selected for analyzing solid‐state kinetics data. The activation energy (Ea) values were calculated via Kissinger and Ozawa models in a period of α = 0.10–0.80. Photostability of the copolymers was investigated. Also, the biological activity of the copolymers against different bacterial and fungal species has been investigated.
