NEW FLUIDS HAVING AN OXETANE STRUCTURE AND IMPROVED CHARACTERISTICS FOR SPECIAL APPLICATIONS

摘要

Oxetane-structure fluids of well-defined composition and free from not completely fluorinated compounds, characterized in that they have at least a perfluoroether chain bound to an oxetane ring, having improved characteristics for special applications, being liquid up to temperatures of at least -70 DEG C., having boiling temperatures in the range of from 50 DEG to 270 DEG C. or higher, and a very high range between the boiling temperature and the pour point.
