  • Process for producing polymers of monoallylamine
    Patent number: 4528347
    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.
