Abstract
Abstract The present invention is directed to a new class of cationic monomers and to polymers thereof. The monomers are quaternary chloromethyl ammonium chlorides having the following general formula: CH.sub.2 ═CR.sub.1 COX(CH.sub.2).sub.n N.sup.⊕ R.sub.3 R.sub.4 CH 2 Cl Cl.sup.⊖ (1) where R 1 =H, CH 3 X=O, NR 2 where R 2 =H, lower alkyl n=2-6 R 3 , R 4 =independently lower alkyl The present invention is also directed to homopolymers and copolymers of the above described class of monomers.
