Abstract:
A method is provided for treating and modifying solid, high molecular weight Lewis base polymers, particularly shaped structures such as fibers, filaments or knitted fabrics, to form branched polymer with improved electrical conductivity, water absorbency and dye receptivity while retaining the essential structural shape. The method comprises heating the polymer in the presence of an aqueous treating solution containing an ethylenically unsaturated monomer which does not readily polymerize under the conditions of treatment and a catalyst which is a source of hydrogen ions or protons. The treatment is carried out at a temperature and for a sufficient time so as to effect essentially single molecule addition of the monomer pendent to the polymer chain with substantially no graft polymerization of the monomer to the polymer. A particularly preferred embodiment of the method is the treatment of nylon 6,6 knitted fabric with an aqueous solution of acrylamide and hydrochloric acid for about one hour at 95.degree. C. to 100.degree. C.

Abstract:
A process for forming cloth-covered cushion articles. A mold is provided having the shape of the desired cushion article. In one form, a cloth covering is drawn into the mold. Foamable material is poured into the mold and cured to form the cushion article. The covered, cured article is removed from the mold and heated to at least the heat-fixable fiber set temperature of the cloth, as the cured foam acts as a male mold to hold the cloth in contour during heat setting. In another form, the foam is poured directly into the mold and cured. The cloth covering then is placed over the cured cushion and set.
