ALKYLKETONE FLUOROTELOMERS, METHODS FOR THE PRODUCTION THEREOF (VARIANTS) AND A METHOD FOR PRODUCING FUNCTIONAL COATINGS BASED THEREON

摘要

The invention relates to producing agents which are used for forming coatings which exhibit the properties intrinsic to polytetrafluoroethylen, i.e., resistance to chemical aggressive media, antifriction and water-repellent properties, in particular to fluor-contaning telomers and to methods for producing coatings based thereon. The inventive method for producing alkylketone fluorotelomers involves carrying out a free-radical telomerisation reaction of unsaturated perfluorolefins (for example tetrafluoroethylene TFE) in a telogen liquid medium with the ratio of TFE/telogen 0.5-20/100. In the preferred variant, the reaction is carried out with the ratio of TFE/telogen (0.7-3)/100 in such a way that a telomer colloidal solution is formed, which solution is used for applying heat-resistant highly-adhesive coatings the thickness of which ranges from 1 to 5 mkm.
