Abstract
The invention relates to a method of fixing copper salts on articles of synthetic polymers such as described in copending U.S. Pat. application Ser. No. 353,730 filed Apr. 20, 1973, now U.S. Pat. No. 3,940,533, patented Feb. 24, 1976; it also concerns articles and particularly, textile articles which have been obtained by the process as well as all materials containing them. The process involves subjecting the articles to the action of hydrogen sulfide and then to the action of a copper salt, characterized by the fact that the treatment with the copper salt is carried out in the presence of polyphenol. The articles obtained may be used, because of their good antistatic properties, to the manufacture of floor or wall coverings and, because of their good conductivity, to the manufacture of heating articles (partitions, clothes, industrial heating articles, etc.).
