FIELD: chemistry.
SUBSTANCE: polyacrylonitrile fibre is saturated with a mixture containing monomers of para-phenolsulphonic acid with formalin in dispersed graphite. Resin is then synthesised on the surface and in the structure of polyacrylonitrile fibre for 30 minutes and then moulded at pressure 0.1 MPa. The components are in the following ratio in pts.wt: polyacrylonitrile fibre: mixture of monomers: dispersed graphite = 1:15:0.5-1.5.
EFFECT: invention enables to obtain a polymer moulding material with ion-exchange properties and low electrical resistance.
