Abstract
In a process for producing a polymer of monoallylamine comprising polymerizing monoallylamine, the polymerization is carried out using as a monomer inorganic acid salts (e.g., hydrochloride, sulfate, etc.) of monoallylamine in the presence of an azo type radical initiator. By the process, polymers of monoallylamine having a high degree of polymerization can be obtained in high yield.
Claims16
A process for producing a polymer of monoallylamine or a salt thereof which comprises polymerizing an inorganic acid salt of monoallylamine in a polar solvent in the presence of an azo type initiator selected from azo compounds represented by formulae (III), (IV), (VII) and (VIII):
- ##STR7## wherein R.sub.1, R.sub.2, R.sub.3 and R.sub.4 each represents, which may be the same or different, a hydrocarbon group;
- R.sub.1 and R.sub.2 or/and R.sub.3 and R.sub.4 may be combined to complete a ring together with the carbon atom attached thereto;
- and n represents 0 or an integer of 1 to 4.
