EFFECTS OF GAMMA RAYS ON AQUEOUS SOLUTION OF POLYVINYL ALCOHOL
The general treatment developed in previous papers is applied to the case where the aqueous solution of polyvinyl alcohol is irradiated by gamma rays, and the results are compared with Danno's measurements. The behaviors of irradiated aqueous solution of polyvinyl alcohol before and after gelation are well explained by the author's general theory. It is concluded from the analysis that end-linking instead of crosslinking occurs in the solution, also that only one molecular end out of the two, which are produced by molecular scission of a polymer, links with a monomer unit of another polymer molecule. It is also shown that if any impurity, especially oxygen, is not contained, the intrinsic viscosity of polyvinyl alcohol increascs with radiation dose. (auth)
