<p>This invention relates to an improvement in a process for preparing reinforced, artificial sausage casings wherein a tubular porous web is passed through a die, impregnated with a polymeric dope, and the polymer regenerated. The improvement resides in employing a porous web having incorporated therein from about 25 to 500 ppm based on the dry weight of the porous web of an alkyl imidazoline ethoxylate of the formula N---CH2 PARALLEL ¦ R-CCH2 R-CCH2 ANGLE N ¦ (CH2CH2O)xH wherein R is a fatty acid radical having from 10 - 22 carbon atoms in the structure and x is a number from about 3 - 10.</p> |
