    摘要: A method for preparing a stretched polymeric material of high strength and high modulus which comprises shaping a dilute solution of a synthetic polymer having an average molecular weight of not less than 3.times.10.sup.5, followed by cooling to make a gel-like filament or film, and stretching the resultant gel-like filament or film at a high stretch ratio, characterized in that a solution or dispersion of (a) the gel-like globules of said synthetic polymer having the solvent occluded therein or (b) the fine powders of said synthetic polymer having an average particle weight of not more than 5.times.10.sup.-5 mg per particle in a solvent is used as or for preparation of said polymer solution to be shaped.
