Abstract

Ion-exchange resins in particle form are made by causing particles of a cross-linked copolymer, which may or may not possess ion-exchange properties, to imbibe a monomeric liquid mixture of two compounds, containing one and two double bonds respectively and polymerizing the imbibed liquid within the copolymer, the ion-exchange properties or additional ion-exchange properties (if desired) being imparted to the resin after the imbibition. The particles may result from suspension polymerization or from grinding larger pieces. The liquid mixture may include a diluent, which may be removed, if desired, after imbibition. The imbibed liquid may be polymerized while the copolymer is in suspension. In examples a bead copolymer of styrene and divinyl benzene was (1) chlormethylated, allowed to imbibe a mixture of styrene and divinyl benzene containing benzoyl peroxide and heated in water to polymerize the liquid. The product was swollen in ethylene dichloride, aminated with triethylamine and finally heated with sulphuric acid whereby both quaternary ammonium and sulphonic acid groups were introduced; (2) swollen in ethylene dichloride and heated with sulphuric acid. The sulphonated product was stirred with an aqueous mixture of methacrylic acid and ethylene dimethacrylate containing potassium persulphate, which was polymerized and the product warmed with sodium chloride solution to form a resin containing both sulphonic acid and carboxyl groups; (3) small particles (passing a 52-mesh sieve) of a bead styrene-divinyl benzene copolymer were immersed in a mixture of styrene and divinyl benzene and polymerization effected, resulting in an increase in size of the particles ( 6/7 retained by the 52-mesh sieve). The ion-exchange properties may be imparted to the resin before and/or after the imbibition. A batch of particles of low average size may be similarly treated to increase their average diameter and narrow the size range. The process may also be used to increase the degree of cross-linking by using sufficient monomer containing two double bonds in the imbibed liquid mixture to cross-link the monomer containing one double bond to a greater degree than the original copolymer.
