Molecular weight-viscosity relationship of gamma-irradiated octadecyl vinyl ether and octadecyl methacrylate

Octadecyl vinyl ether and octadecyl methacrylate monomer were polymerized by means of gamma radiation from a cobalt‐60 source. The weight‐average molecular weight and the intrinsic viscosity of the resulting polymers were determined. The constants K′ and a were 0.25 × 10−4 and 0.75, respectively, for poly(octadecyl methacrlylate) and 22.4 × 10−4 and 0.35, respectively, for poly(octadecyl vinyl other).
