| abstract |
The present invention relates to a special polymerization process, i.e. aqueous dispersions carried out in the presence of carboxylic acids, salts, esters or peroxides, sulfonic acids or salts or esters, or alkanols or esters thereof, or ketones, in addition to conventional initiators, dispersants and chain transfer agents. By using the fluorocarbon polymer prepared by the polymerization method as a low molecular weight fluorocarbon polymer, thermally stable release coatings of essentially non-fluorocarbon polymers and low molecular weight fluorocarbon polymers are non-choking, i.e., to be coated. A method of preventing the formation of waxy deposits on processed articles.n n n Alternatively the additive may be a fluorosurfactant containing a carbon-hydrogen bond and also acting as a dispersant in the polymerization medium. |
