ABSTRACT:
Disclosed are a polymer emulsion prepared by neutralizing a seed polymer with an acid or a salt or by quaternizing it with a quaternizing agent and a method of preparing the polymer emulsion. The surfaces of the emulsion grains are very densely cationated. The seed polymer is formed by polymerizing a monomer of formula (I) or a mixture of the monomer (I) and copolymerizable ethylenic unsaturated monomer(s) (II) and a seed latex of a carboxyl-modified synthetic rubber latex or synthetic resin emulsion. ##STR1## R.sub.1 is H or CH.sub.3 ; R.sub.2 is a 2-5C alkylene; R.sub.3 and R.sub.4 each are H or a 1-5C alkyl; A is--COO--or--CONH--; and R.sub.1, R.sub.3 and R.sub.4 are so selected that the monomer is hardly soluble or insoluble in water. As a consequence of being very densely cationated by post-modification, the cationic polymer emulsion is useful in various fields as binders, fixers or other additives.
