    摘要： The present invention provides expandable plastics having a molecular weight of 50,000 to 500,000 which comprises the following structural units (I), (II) and (III) giving a foam having heat resistance and fine structure by heating, the molar ratio of (I+II) to (III) being 1 to 0.6-1.5 and the proportion of (I) being 5 to 50 wt. % of the total components: ##STR1## wherein R represents a hydrogen atom or a methyl group. When the copolymer, the expandable plastics, of the present invention is used, white foams having a very fine texture are obtained without using special foaming agents, and besides the heat resistance of the foams is high and the amount of water absorbed thereby is little. The foams of the present invention, therefore, can be used in a wide range as soundproofing materials and heat insulators for which the conventional foams cannot be used because of their low heat resistance, and substitutes for honeycomb structures used in airplanes.

    摘要： A spinning solution for acrylonitrile polymers is disclosed, which has a viscosity of 30 to 520 poises (at 50.degree. C.) and which comprises an acrylonitrile polymer having a reduced viscosity of not less than 4.0, a solvent, and water, wherein the water concentration and the polymer concentration fall within the range in the drawing surrounded by straight lines connecting point A (1 wt % and 30 wt % respectively), point B (1 wt % and 10 wt % respectively), and point C (10 wt % and 10 wt % respectively). The spinning solution exhibits satisfactory spinnability in spite of its high polymer concentration and provides void-free acrylonitrile fibers having a highly circular cross-section and excellent mechanical strength.
