To improve the static electricity of acrylic fiber, chemical method was introduced. Polyacrylonitrile copolymer with pyrrolidone group(PBPGP) was synthesized by copolymerization of acrylonitrile(AN) and methylacrylate(MA) initiated by aqueous sulfite-chlorate redox system under the presence of polyvinylpyrrolidone(PVP). The fibers from PBPGP and virgin acryl polymer(PAN) were manufactured by wet-spinning at DMF system. The physical properties of fibers were investigated by IR, SEM, DSC, Rheovibron, Instron and Static Honestometer. Within measured range the physical properties of PBPGP and PAN fibers were nearly on a par except static the electricity the electricfied potential of PBPGP fiber differ little from that of PAN fiber but the half-life of static electricity of PBPGP fiber was markedly shorter than that of PAN fiber.
