摘要:
N-substituted secondary monoallylamine salts can be easily polymerized in a polar solvent by using as catalyst a water-soluble radical initiator containing azo group in the molecule, and polymers with a high degree of polymerization can be obtained therefrom in a high yield.

摘要:
A small-globular crosslinked polymer of monoallylamine swellable but insoluble in water can be obtained by crosslinking a part of the amino groups of a monoallylamine polymer with formaldehyde or a compound having, in its molecule, at least two functional groups reactive with primary amino group.
