ABSTRACT:
Infusible and insoluble styrene copolymeric fibers are prepared by copolymerizing styrene with an olefinic compound having at least one functional group selected from haloalkyl group, amino group, carboxyl group, carbonic acid ester group, carbonic acid halide group, hydroxyl group, amido group, nitrile group and halogen atom, melt spinning the resulting styrene copolymer into fibers and treating the formed fibers with a cross-linking agent to form three dimensional cross-linkages in the fibers.
