The fibrous polymeric material based on polyvinyl chloride contains at least one antiseptic mercury derivative distributed in its polymeric structure in the form of a substantially molecular and practically non-releasable dispersion. The preferred mercury derivatives have the following general formula: ##STR1## in which Y is H or HgX. If the concentration of the derivative is equal to at least 0.5% by weight, relative to the chlorofiber, the latter has a permanent antiseptic character. This material is obtained by incorporating the above-mentioned derivative into the collodion when the chlorofiber is spun.
A fibrous polymeric material based on polyvinyl chloride which contains at least one antiseptic mercury derivative distributed in its polymeric structure in the form of a substantially molecular and practically non-releasable dispersion, said derivative being present in a concentration of at least 0.25 mg of mercury/g of chlorofiber and containing at least one benzene ring and comprising on the one hand at least one radical HgX, in which X is selected from F, Cl, Br, I, OH, CH.sub.3 COO, CN, SCN, NO.sub.3 and OB(OH).sub.2, and on the other hand, bonded to a benzene ring, at least one group --OR or --COOR, in which R is a functional group which is capable of partaking in a polymerization or polyaddition reaction, said derivative being not fixed on the polymeric structure of the material by a reaction of polymerization or of polyaddition, but being distributed on its polymeric structure in the form of a molecular and practically non-releasable dispersion.
