ABSTRACT:
The use of a radical initiator of azo compound type represented by the following general formula (I) enables polymerization of an inorganic acid salt of monoallylamine, whereby a polymer of an inorganic acid salt of monoallylamine having a high polymerization degree can be obtained in a high yield, ##STR1## [In the above formula, A and B independently are an alkylene group of 2 to 3 carbon atoms which may have one or more substituents on the carbon atom or atoms; R.sub.1, R.sub.2, R.sub.3, R.sub.4, R.sub.5 and R.sub.6 may be same or different and independently are a hydrogen atom or a hydrocarbon group; and X is a monovalent anion selected from the group consisting of Cl, Br, NO.sub.3, HSO.sub.4, H.sub.2 PO.sub.4, HSO.sub.3, HCOO, CH.sub.3 COO, ##STR2## and CH.sub.3 SO.sub.4.]
