“…The polymer glass‐transition temperature ( T g ), representing the molecular mobility of the polymer chains, is an important phenomenon that influences the material properties and potential applications of a given polymer 7. Recently, we reported some studies on monomer reactivity ratios of methacrylate with alkyl or hydroxyalkyl side groups 8–10. However, many equations that describe the effect of the composition of the monomeric units in the copolymer chain on T g have been reported, such as the DiMarzio equation,11 the Fox equation,12 the Gordon–Taylor equation,13 the Wood equation,14 the Johnston equation,15 and the Couchman equation 16…”
