Abstract

Weakly basic anion exchange resins with tert.-amino gps are prod. from pri. - or Sec. - amino gp. contg. - resins by pre-swelling with dil. HCOOH and then treating with conc. HCOOH and carboxyl cpd. opt. diluted with H2O or an alcohol at initially >=0 degree C and stepwise heating to reflux temp. Esp. suitable for resin prod. from styrene/divinylbenzene copolymers after chloromethylation and amination, and esp. using HCHO in second step.
