Abstract: FILLED POLYMER COMPOSITIONS MADE BY DISSOLVING THE POLYMER BINDER IN A SUITABLE SUBLIMABLE SOLVENT, MIXING THE FILLER MATERIAL WITH THE POLYMER AND ITS SOLVENT, FREEZING THE RESULTING MIXTURE, AND SUBLIMING THE FROZEN SOLVENT FROM THE MIXTURE, REMOVING IT THEREFROM. THE REMAINING COMPOSITION IS THEN SUITABLE FOR CONVENTIONAL PROCESSING, SUCH AS COMPRESSION MOLDING OR EXTRUDING. A PARTICULAR FEATURE OF THE METHOD OF MANUFACTURE IS POURING THE MIXED SOLUTION SLOWLY IN A CONTINUOUS STREAM INTO A CRYOGENIC BATH WHEREIN FROZEN PARTICLES OF THE MIXTURE RESULT. THE FROZEN INDIVIDUAL PARTICLES ARE THEN SUBJECTED TO THE SUBLIMATION.

Abstract: A coated substrate is formed by dissolving in solvent a linear quaternary ammonium polymer of the formula:

WHERE R1 and R2 are each alkyl of 1-10 carbon atoms; R3 and R4 are each alkylene, alkenylene, arylene, aralkylene, alkarylene, alkyleneoxy, alkylenethio of 1 to 100 carbon atoms; n is an integer greater than 2; and X is a halogen selected from Cl , Br and I ; immersing the substrate in the solution and adding to the solution a halogen source selected from the group consisting of Br and I to precipitate on said substrate an insoluble trihalide salt of said polymer.
