Process of forming a polymeric emulsion which comprises copolymerizing in aqueous dispersion an ethylenically-unsaturated monomer containing quaternary nitrogen

The process of forming a self-stabilized surfactant-free polymeic emulsion of a water-insensitive polymer which comprises

• copolymerizing in aqueous dispersion in the absence of surfactants or dispersing agents between 99% and 95% by weight of an ethylenically-unsaturated monomer, within between 1% and 5% of a monomer selected from the class represented by the formula ##STR7## wherein V is an acrylic ester or acrylamido group represented by the formulas CH.sub.2 =CR.sub.4 --COO-- and CH.sub.2 =CR.sub.4 --CONH-- , where R.sub.4 is H or CH.sub.3 ;
• A is an alkylene or substituted alkylene group selected from the class consisting of -- CH.sub.2 . CH.sub.2 -- , -- CH.sub.2. CH.sub.2.CH.sub.2 -- , --CH.sub.2. CHOH.CH.sub.2 -- , and --CH.sub.2. CH(CH.sub.3)-- groups;
• and wherein the quaternary nitrogen group -- N R.sub.1 R.sub.2 R.sub.3 is selected from the class consisting of:
• a. aliphatic tertiary amines wherein R.sub.1 is an alkyl group of from 1 to 7 carbon atoms;
• R.sub.2 is an alkyl group of from 1 to 7 carbon atoms or a benzyl group;
• R.sub.3 is selected from the class consisting of saturated aliphatic hydrocarbon groups of from 7 to 28 carbon atoms and benzyl groups substituted with a saturated aliphatic hydrocarbon group of from 7 to 28 carbon atoms;
• b. groups in which N, R.sub.1, and R.sub.2 together from a heterocyclic tertiary amine of the general formula:
• ##STR8## and R.sub.3 is a saturated aliphatic hydrocarbon group of from 7 to 28 carbon atoms,
• and where X.sup.- is selected from the class consisting of F.sup.-, CI.sup.-, Br.sup.-, I.sup.-, CH.sub.3 SO.sub.4.sup.-, C.sub.2 H.sub.5 SO.sub.4.sup.-, and ##STR9##
