    Abstract: PURPOSE:To obtain the titled polymer which can be converted into a polymer useful for adsorption, ion exchange, enzyme immobilization, etc., by reacting a specified insolubilized arom. vinyl polymer with a haloacetamidomethylating agent. CONSTITUTION:A (co)polymer of an arom. vinyl monomer such as styrene which is used as a starting material, is reacted with a haloacetamidomethylating agent (e.g. N-methylolchloroacetamide) of formula I (wherein X is halogen; R', R'' are each H, lower alkyl, aryl, aralkyl; Y is H, lower alkyl, acryl) in the presence of formaldehyde, a swelling agent (e.g. nitropropane) and an acid catalyst (e.g. sulfuric acid), to produce an arom. vinyl polymer having a functional group of formula II. The halogen of the functional group of formula II can easily be substituted with other functional groups, e.g. amino group to produce a polymer having a group of formula III. This polymer exhibits excellent performance in immobilization of enzymes and bacteria, or as an adsorbent for macromolecular compds.

    Abstract: PURPOSE:To obtain the title yarn having improved strength, transparency, gloss, and hygroscopicity at a low cost, by melt spinning a blend of specific polymers, and by drawing a taken-up yarn with a specific moisture content and contact pressure. CONSTITUTION:Thermoplastic polymers having the second-order transition point of at least 100 deg.C comprising about 0.2-2.0wt% of acrylonitrile-containing polymers are blended and melt spun into filament yarns, which are oiled with about 4-9%, preferably 5-8%, of moisture, and taken up under a drum contact pressure of 0.6-5.0kg, preferably 2.0-4.0kg, and drawn. The winding density of the undrawn yarn is preferably about 0.65-0.85g/cm . According to the method, the following effects are produced: Increased sprinning speed suppression of longitudinal yarn swell, stabilization of package forms, increased widing density, enlarged packages, improvement in drawing operating efficiency, and sharp increase in drawing speed.
