Some copolymers of 2‐(3‐phenyl‐3‐methylcyclobutyl)‐2‐hydroxyethyl methacrylate (PCHEMA) with acrylonitrile (AN) have been prepared in the presence of 2,2′‐azobisisobutyronitrile in 1,4‐dioxane solvent at 60 °C. The copolymers have been characterized by infrared, 1 H and 13 C NMR techniques. The percentages of PCHEMA and AN in the copolymers have been established by elemental analysis. The glass transition temperatures as a function of PCHEMA (from 1 to 7) in the copolymer change from 88 to 103 °C. Initial decomposition temperatures as a function of PCHEMA in copolymer show a decrease from 310 to 262 °C. The monomer reactivity ratios of copolymerizations are calculated by using both Kelen–Tüdös and Fineman–Ross equations. The antifungal effects of these copolymers have also been investigated using Saccharomyces cerevisiae. © 1999 Society of Chemical Industry
