Crosslinking copolymerization of N-vinylformamide (NVF) and divinylbenzene (DVB) has been carried out in reverse suspension in presence of water which serves as porosity generating feature (porogene). The continuous phase was provided by silicone oil or paraffin oil. In silicone oil the copolymer resulted in form of regular spheres what was not the case when paraffin oil was used. After base hydrolysis anion-exchangers were obtained having primary amine groups attached to the backbone. Exchange capacity, degree of swelling, water content in air conditioned resin and the specific surface were determined.
Key words: N-vinylformamide, polyvinylamine, anion-exchangers, suspension polymerization
