Macroporous strong basic acrylic anion exchange resin

Macroporous strong basic acrylic anion exchange resin

[Structural formula]

[Physical and chemical properties] The product is white to light yellow opaque spherical particles with a wet apparent density of 0.

[Preparation method] The copolymer of methyl acrylate and divinylbenzene is aminated and alkylated to obtain acrylic acid-based strong basic anion exchange resin

Acrylic esters are used as monomers, divinylbenzene, etc.

In addition, N-(N'-dialkylamine) methacrylamide and divinylbenzene can also be copolymerized to directly obtain resins with tertiary amine groups

[Application] Mainly used for water treatment and decolorization

The copolymer of methyl acrylate and divinylbenzene can be aminated with various amines to make acrylic acid-based weak base resin

Cross-linked polymethyl acrylate and polyvinyl polyamine can be aminated to obtain a weakly basic resin:

This reaction produces additional crosslinks

The copolymer of methyl acrylate and divinylbenzene reacts with tetraethylenepentamine at 130～150℃ under the swelling of diethylbenzene or acetophenone to form polyamine resin with an exchange capacity of 7.

Copolymerization of N-(N'-dialkylamine) methacrylamide and divinylbenzene can directly obtain resin with tertiary amine group:

Here R=—CH ₃ ,—CH ₂ CH ₃ ,—C ₃ H ₇ ,—C ₃ H ₉ or—C ₆ H ₁₃

Compared with styrene-based anion exchange resins, the advantages of strongly basic acrylic resins are more prominent.

Alkylation with chloroethanol under alkaline conditions can be made into polyhydroxy quaternary ammonium resin
