ABSTRACT:
The present invention provides an novel polymer having 1-2,000 equivalents of an N-sulfoamino group/10.sup.6 g of weight of the polymer.
The polymer has excellent dispersibility of inorganic fine particles, hygroscopicity, and dye-affinity. The polymer provides a binder resin in which a magnetic or non-magnetic metal or metal oxide can highly be dispersed. The polymer also provides a magnetic recording medium which is excellent in electromagnetic conversion characteristic, surface smoothness, adhesion to non-magnetic substrates, and durability. The polymer provides a magnetic recording medium with improved travelling, travelling durability, signal-to-noise ratio, and drop-out. The polymer also provides a polyester fiber which has a high fiber strength and an excellent hygroscopicity and can be colored with cationic dyes.
