Abstract
The invention is directed at novel fluorinated amide compounds of formula (1): ##STR1## wherein Rf is a divalent perfluoroalkylene or perfluoro-polyether group, X is a group of formula (2), (3) or (4), and m is an integer inclusive of 0. ##STR2## R.sub.1 is a monovalent hydrocarbon group, and R.sup.2 is a divalent hydrocarbon group. These compounds can be used to obtain elastomers or cured resins having a high fluorine content and a low surface energy, making them effective as starting materials in the production of chemical and isolvent-resistant elastomeric materials, parting agents, and water repellents.
