Aminoalkyl methacrylate derivative monomer"METHACRYLATE" Products

What are great about Sanyo Chemical's aminoalkyl methacrylate derivative monomer "METHACRYLATE" products

1

Addition of various functions (hydrophilicity, antistatic properties, etc.) by introducing cationic groups into polymers

Sanyo Chemical's "METHACRYLATE" products are aminoalkyl methacrylate derivative monomers with double bonds and tertiary amino or quaternary ammonium groups in the molecule. By polymerization alone or copolymerization with other vinyl monomers, polymers with water solubility, hydrophilicity, antistatic properties, conductivity, adsorption and reactivity with anionic compounds, etc. can be obtained.

Polymerization

The "METHACRYLATE" products of aminoalkyl methacrylate derivative monomers can all be polymerized alone or copolymerized with other vinyl monomers. Polymerization can be easily initiated by ordinary azo or peroxide radical initiators, as well as by ultraviolet light or heat. 

"METHACRYLATE" products are aminoalkyl methacrylate derivative monomers that can be functionalized by introducing cationic groups into polymers.
