Novel Porous Sheets Made Directly from Acrylonitrile or Polyvinyl Alcohol
Source abstract
Abstract
Dilute aqueous solutions of acrylonitrile and polyvinyl alcohol were frozen in sheet form. Ionizing radiation from a cobalt-60 source was used to achieve polymerization in a network of voids between ice crystals. Dosages were 5 to 64 megarads for acrylonitrile at -100°C and 1 to 25 megarads for polyvinyl alcohol at -20°C. Subsequent to thawing and evaporation, stable fabric-like webs were obtained.
