    Abstract: A novel, easily regeneratable, high-performance chelating resin and process for preparing the same. More in particular, a crosslinked polymer consisting mainly of an aromatic vinyl monomer having a polyalkylene polyamine functional group containing an iminodipropionic acid group or an iminodi- Alpha methylpropionic acid group, and process for preparing the same. Because chelating resins of the present invention have pendant functional groups attached pendantly thereto, at least one iminodipropionic acid group or iminodi- Alpha -methylpropionic acid group and at least two nitrogen atoms, it has a very large capacity for adsorbing heavy metals per unit volume of chelating resin. Moreover, because the stability of the chelate of said iminodipropionic acid group or iminodi- Alpha -methylpropionic acid group with heavy metal ions is relatively low, regeneration from an adsorbent with heavy metals is easy. According to the process a high-performance chelating resin can be prepared, having a very high ability to absorb heavy metals. It is easily regeneratable, which has heretofore been inexpensively unattainable by conventional processes and is produced by a new process which is high in industrial practical value.

    Abstract: Sheet-like materials for example for use as synthetic fabrics, comprising a bundle of fine fibers having a maximum deformation ratio of about 12% and a minimum apparent density of 0.21 g/cm3, said fine fibers having a maximum denier of about 0.45 are disclosed. The materials are made by forming a fiber aggregate of multi-component fibers, removing one component from the fibers, eg. by dissolution, to convert each fiber to a bundle of fine fibers consisting of the residual component, shrinking and heat treating the aggregate and impregnating the aggregate with a binder.
