AbstractSyndiotactic poly(methacrylic acid) has been partially esterified with diazotoluene or diazodiphenylmethane in extension of work carried out with diazomethane1. The sequence statistics of the resulting cosyndiotactic benzyl methacrylate–methacrylic acid and diphenylmethyl methacrylate–methacrylic acid copolymers have been studied with 1H‐NMR ...
