Fluorinated polyurethanes and polyurethane-ureas, of heat-processable, elastomeric type, constituted by rubber-like blocks and hard blocks, comprising segments derived from:

Fluorinated polyurethanes and polyurethane-ureas, and methods for

A method of reducing the static and dynamic coefficients of friction and improving the wear life of thermoset elastomeric articles is disclosed. The elastomeric articles are fluorinated in the presence of a hydrogen fluoride scavenger under conditions sufficient to reduce said friction coefficient and improve said wear life, without promoting degradation of the tensile properties of the articles.

Fluorination of articles molded from elastomers

A method of producing fluorinated elastomeric articles having reduced coefficients of friction, improved wear life and improved resistance to fluid permeability. A thermoplastic elastomeric article is exposed to gaseous fluorine in a reactor vessel under reaction conditions sufficient to create a fluorinated material on the external portions of the elastomeric article, which fluorinated material extends inwardly into the matrix of the article, without promoting degradation of the tensile properties of the article.
