Possible to provide various functions to polymers by our modification technology
Carbamoyl group(-CONH2) can be converted into primary amino group(-NH2) which is reactive by Hofmann reaction of polyacrylamide.
Tertiary amino group in polyamine resins can be converted into quaternary ammonium group by additional reaction with quaternizing agent.
Possible to obtain aqueous emulsion by quarternization of amino group in fatty acid amide resins
Possible to control degree of quarternization and particle size of fatty acid amide resin emulsion
(1) Possible to control molecular weight, degree of cross-linkage, and cationicity of resins by controlling modification level of epichlorohydrin to polyamide-polyamine resins
(2) Possible to control amount of azetidinium ring (AZR) formed in polyamide-polyamine resins
(3) AZR is highly reactive with amino group or carboxylic group
It is possible to design a polymer with anionic properties.
It is possible to modify the physical properties (e.g., softening point and acid value) depending to the purpose.
Emulsification by alkali neutralization is possible.
Possible to control molecular weight and cationicity depending on the degree of formation of urea-adducts and crosslinked structure formed by the reaction of amino group of polyamide-polyamine resins with urea
