Aminoethylated Acrylic Polymer: POLYMENT™ Aminoethylated Acrylic Polymer, Aminated acrylicpolymer

Basic Information

POLYMENT™ is an acrylic polymer containing primary amino group due to the grafting of polyethyleneimine in its side chain. POLYMENT™ is a polyacrylamine that has the features of both polyethyleneimine and acrylic polymer. POLYMENT™ shows high reactivities thanks to its amino group and superior adhesiveness to various base materials. Cationic acrylic polymers are generally known as being
tertiary amine and quaternary ammonium polymers, such as dimethylaminoethyl acrylate or
dimethylaminoethyl methacrylate polymer.
POLYMENT™ is the only cationic acrylic polymer with primary amine in the world.

Manufacturing Method

Using the reactivity of ethyleneimine and carboxyl groups, acrylic acid copolymers can be
easily converted to acrylic polymers with primary amines.

Features and Properties

POLYMENT™ is grouped into two types according to its form.
Type one is a water-dilutable resin that can be diluted in water by neutralizing amino groups, and type two is a solvent-based resin that is synthesized under solvent conditions.
Both types have primary amino groups, which gives them excellent reactivity with epoxy resins, and superior adhesion to base materials such as plastics and metals, etc.
