Abstract: Linear poly(hydroxyethyl methacrylate) has been prepared by γ-radiation irradiation polymerization in 20%(v/v) alcohol solution.
Dyad, triad and pentad comonomer distributions for the polymer were observed in ¹³C NMR spectrum obtained at 20 MHz and 35℃ condition. Assignments were made by comparing observed intensity distribution for each carbon type with those calculated assuming Bernoullian statistical model. The results show that the polymerization process conform with that of Bernoullian.
The poly (hydroxyethyl metharylate) prepared by this method has a tactic triad content of 70.2% syndic., 27.2% hetero., and 2.6% iso..
