Abstract
Monomeric acrylic acid when placed between two polymeric films may be polymerized almost explosively at a dose of 0.3 Mrad with electrons. The resultant exotherm leads to bonding of the two films and the preparation of an interlaminar layer of polyacrylic acid. Changes in oxygen permeability are found for the resultant sandwich. The exotherm and the resultant bonding is dependent on the dose rate, dose, and the volume of acrylic acid used for the interlaminar layer. The results qualitatively follow the mechanism for explosive polymerization discussed by Semenov and more recently by Chachaty, Magat, and Ter Minassian.
