The present invention provides an novel polymer having 1-2,000 equivalents of an N-sulfoamino group/10⁶ 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.
本发明提供了一种新型聚合物,该聚合物具有 1-2,000 个当量的 N-磺酰胺基/10⁶ g 的重量。
该聚合物具有优异的无机微粒分散性、吸湿性和染料亲和性。该聚合物提供了一种粘合剂树脂,磁性或非磁性金属或金属氧化物可在其中高度分散。这种聚合物还能提供一种在电磁转换特性、表面平滑度、与非磁性基底的粘附性和耐用性方面都非常出色的磁记录介质。该聚合物提供的磁记录介质具有更好的磁路传输性能、磁路传输耐用性、信噪比和掉电现象。该聚合物还提供了一种聚酯纤维,它具有较高的纤维强度和出色的吸湿性,并可使用阳离子染料着色。
