  • Novel complexes of polyoxazolines or polyoxazines and halogens, interhalogens or pseudohalogens and process for preparing same
    Patent number: 4186191
    Abstract: Novel solid complexes of 2-oxazoline and 2-oxazine polymers and halogens, interhalogens or pseudo-halogens are prepared by contacting a poly-2-oxazoline or poly-2-oxazine whose backbone comprises a plurality of ring-opened units of an oxazoline or oxazine monomer of the general formula ##STR1## wherein R and R.sub.1 -R.sub.4 are each independently hydrogen, alkyl, aralkyl, phenyl or inertly-substituted phenyl and n is zero or one with a halogen, interhalogen or pseudo-halogen. The complexes are soluble in a variety of conventional solvents (e.g., water, methylene chloride, acetonitrile, methanol, tetrahydrofuran and isopropanol).
    Type: Grant
    Filed: December 11, 1978
    Date of Patent: January 29, 1980
    Assignee: The Dow Chemical Company
