Description
Ionic polymerizations of cyclopentadiene (CPD), ethylene oxide (EO) and some other monomers in a matrix of butyl chloride (BC) were achieved by low-temperature postradiation polymerization during softening of the glassy system. To conduct the polymerization, various amounts of the monomers were dissolved in BC at 273 K, and cooled to 77 K. On slow reheating of such radiolysed systems in the range of the matrix devitrification (Tsub(g) approx.= 97 K), polymerization was observed. Evidence was obtained to indicate cationic mechanisms for CPD and EO polymerization in a glassy BC matrix. No special techniques for monomer and solvent drying are required. (author)
