AMBERLITE(R) XAD-4 CAS#37380-42-0

Products Description of AMBERLITE(R) XAD-4 CAS#37380-42-0

Ion exchange resin is a kind of functional polymer that can exchange with ions of the same sign in aqueous solution. It is essentially a cross-linked polymer acid or polymer base. Phenolic cation exchange resin was first introduced in 1935, and industrial production began in Germany in 1939 and the United States in 1941. After World War II, polystyrene and polyacrylic acid ion exchange resins were put into production one after another. After the 1960s, macroporous ion exchange resins were developed. According to the different exchange groups, they are divided into cationic and anionic types; according to the difference in the degree of ion dissociation, they are divided into strong acid, weak acid, strong base and weak base. It can also be divided into gel, macroporous and ion exchange membrane according to the appearance shape and physical properties. Special varieties such as chelating resin, amphoteric resin, oxidation-reduction resin, etc. have also been developed.
