Process for the production of low-molecular-weight allylamine polymer or addition salt thereof

The present invention relates to processes for industrially advantageously producing, in high yields, an N,N-dialkylallylamine polymer or an addition salt thereof, a copolymer of N,N-dialkylallylamine and monoallylamine or an addition salt thereof, and a copolymer of N,N-dialkylallylamine and diallylamine or an addition salt thereof, which are useful for various uses in the field of fine chemicals and particularly useful as a water-resistance-imparting agent for an inkjet ink.

Processes for producing N,N-dialkylallylamine polymers and N,N-dialkyllylamine polymers

Provided is an industrially advantageous process for producing allylamine polymers from various allylamines in an organic solvent with ease and at high yields, and the process comprises polymerizing allylamines in a medium containing an organic solvent in the presence of an azo compound selected from azo compounds of the formulae (I) and (II),

Process for the production of allylamine polymer

Poly(allylamine salt) of high polymerization degree is obtained in high yield by the polymerization of monoallylamine salt with a specified radical-polymerization initiator having in the molecule an azo group. Poly(allylurea) is obtained by reacting said poly(allylamine salt) with cyanic acid salts.

Process for producing poly(allylamine) derivatives
