Abstract: An antistatic acrylic fiber having an electrical resistivity of about 108 OMEGA centimeters or less. The fiber comprises (A) an acrylonitrile homopolymer or copolymer and (B) an antistatic polymer comprising a plurality of polyether segments disposed in said polymer (A), and wherein electrically conductive carbon black is dispersed in antistatic polymer (B). Preferably antistatic polymer (B) extends in the form of long and slender stripes in the polymer (A).

Abstract: PURPOSE:To obtain the title polymer solution decreased in microgel formed and improved in moldability, by adding a radical polymerization inhibitor to a specified acrylonitrile polymer solution after conducting a derived polymerization. CONSTITUTION:Acrylonitrile and 0-10mol% vinyl monomer copolymerizable therewith (e.g., acrylic acid) are subjected to a solution polymerization at 40-90 deg.C in an inorganic or organic solvent in the presence of a radical polymerization initiator (e.g., azobisisobutyronitrile) and a chain transfer agent (e.g., dodecyl mercaptan) to obtain an acrylonitrile polymer solution (A) for the production of an acrylonitrile molding. Component A is mixed with at least one radical polymerization inhibitor selected from among (B) an N-nitrosophenyl compound, a hydrazine compound, an aldoxime compound and a mixture of an N-nitrosophenyl compound with a phenyl compound in an amount of at least 1/2mol per mol of the radical polymerization initiator remaining in the acrylonitrile polymer.

Abstract: PURPOSE:To obtain the titled solution having remarkably decreased amount of microgel in the polymer and giving reduced load in maintenance of a filter, by controlling the amount and charging order of each raw material compound in the solution polymerization in a batch polymerization reactor by continuous operation. CONSTITUTION:A batch polymerization reactor is charged with (A) acrylonitrile. Prior to the charge of 50wt.% of the acrylonitrile based on the whole amount to be charged, the reactor is charged with (B) a vinyl compound having destructive chain-transfer action (e.g. acrylic acid) or (C) a chain-transfer agent (e.g. hypophosphorous acid) in amounts corresponding to >=10wt.% of the charging amount of each component. After completing the charge of the entire amount of the components A, B and C according to conventional process, the batch polymerization reactor is continuously operated to effect the solution polymerization of the components A and B in the presence of the component C to obtain the objective solution. The polymerization initiator is preferably charged first at the stage when the charge of the components A, B and C are completed.
