Abstract: 1. A SOLVENT-RESISTANT FILAMENTARY STRUCTURE COMPRISING AT LEAST 20% BY WEIGHT OF AROMATIC NUCLEAR STRUCTURAL UNITS DERIVED FROM AN AROMATIC MONOVINYL MONOMER, 2 TO 40 OUT OF 100 OF SAID AROMATIC NUCLEAR STRUCTURAL UNITS BEING CROSS-LINKED BY CROSSLINKAGES OF THE FOLLOWING FORMULA (I)

>CH-X-SO2-X''-CH
WHEREIN X AND X1 ARE THE SAME OR DIFFERENT AND EACH REPRESENTS AROMATIC NUCLEAR STRUCTURAL UNITS DERIVED FROM AN AROMATIC MONOVINYL MONOMER, SAID FILAMENTARY STRUCTURE NOT CONTAINING A CROSSLINKAGE EXPRESSED BY THE FORMULA

>CH-X-C(-X'')
WHEREIN X IS THE SAME AS DEFINED ABOVE AND X'' IS THE SAME AS DEFINED ABOVE OR A HYDROGEN ATOM, AND THE REMAINDER OF SAID AROMATIC NUCLEAR STRUCTURAL UNITS, EITHER PARTLY OR WHOLLY, HAVING INCORPORATED THEREIN A METAL-CHELATING GROUP.
