    摘要: Natural suede-like artificial leathers are manufactured by subjecting pile fibrous structures wherein at least the pile portion is composed of separatable composite filaments made by bonding different polymers having mutual low adhesive affinity with each other, the cross-section of which is constituted of a radial segment (A) and segments (B) complementing the radial segment or a radial segment (A), segments (B') corresponding to said radial segment and having wedge-shaped concave portions directing to the center and wedge-shaped segments (C) complementing said concave portions, to at least one of a heat treatment and a swelling treatment to shrink said fibrous structure at least 10% in the area, impregnating or coating said fibrous structures with a synthetic polymer solution or emulsion, coagulating said polymer solution or emulsion, drying the thus treated pile fibrous structure and then buffing said piles to raise naps.

    摘要: A novel fluorine-containing crosslinkable copolymer comprising fluorine-containing monomer units each having a sulfonyl chloride group and monomer units of at least one ethylenically unsaturated compound is disclosed. The present fluorine-containing crosslinkable copolymer has a specific range of a sulfonyl chloride group content and can be easily crosslinked to give a fluorine-containing elastomer which is excellent in heat resistance and chemicals resistance.
