IMIDAZOLINES IN PREPARING FIBROUS ARTIFICIAL SAUSAGE CASINGS

摘要

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 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.
