Abstract:

The internal polymerization f two monomers, acrylonitrile and methyl methacrylate, in three different types of paper was accomplished using the free radical-catalysis mechanism. Modified paper products containing 5 to 35 of polymer were prepared. The tensile properties both wet and dry and the stiffness increased on each type of paper with increases in polymer content. The polymerization of methyl methacrylate in each of the three types of paper resulted in large increases in the wet and dry tensile strength of the paper. Increases in the wet and dry tensile strength of filter paper were realized with the acrylonitrile treatment. Onl minor improvements were realized with the acrylonitrile treatment of kraft paper and target paper. The stiffness of the kraft and target papers increased by appr ximately 1.6 for every 1 increase in polymer content and the filter paper stiffness increased at approximately twice this rate. Some fungus resistance was imparted to the paper by the internal polymerization of methyl methacrylate. Author
