Bulk polymerization of isobutyl vinyl ether was studied at 25/sup 0/C in a wide dose rate range, 8.2 to 277 rad/sec by ..gamma.. rays and 8.8 x 10/sup 3/-2.2 x 10/sup 5/ rad/sec by electron beams. At low dose rate, 8.2 to 277 rad/sec, only the radical polymerization took place. At high dose rate exceeding 8.8 x 10/sup 3/ rad/sec, cationic polymerization was found to occur in addition to the radical polymerization. DP/sub n/ of the product at high dose rate was 9 to 10. Further drying of the monomer increased R/sub p/, and molecular weight of the product formed by cationic mechanism also increased. 9 figures, 1 table.
