According to the invention the material, in particular a textile, includes in its polymeric structure grafts forming complexes with at least one metal ion possessing recognized antiseptic activity. These grafts are formed by polymerization of unsaturated monomers with a complexing function, including the phosphate of ethylene glycol methacrylate or a polymerizable derivative of quinoline such as acryl 8-hydroxy quinoline. The process of preparation comprises a first step of grafting, for example by electronic irradiation of the material and impregnation with a bath of monomer, and a second step of impregnation of the grafted material with one or serveral baths containing the metal ion(s), such as copper, zinc, tin, mercury.

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.

The novel antiseptic mercurial derivatives according to the invention have at least one benzene ring and comprise: a) 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, OB(OH).sub.2, b) and, bonded to a benzene ring, at least one group--OR or--COOR in which R is a functional group capable of intervening in a reaction of polymerization or of polyaddition. The preferred derivative is 2-chloromercuri 4-tertiobutyl phenol allyl-ether. They may intervene in grafting reactions for the protection of a polymeric support, or in reactions of copolymerization.

Novel organic mercurial derivatives with antiseptic character

New mercurobutol derivatives characterized in that they comprise at least one functional group, bonded to the mercurobutol phenol ring, which functional group being capable of intervening in a polymerization or polyaddition reaction, and said derivatives having the bioactive properties of mercurobutol, even after such reaction. These new derivatives can intervene in a grafting operation either as termination agent or a polymerization agent. These new derivatives, when grafted on a support, give it protection against bacteria, mushrooms and other micro-organisms.
