SYNTHESIS OF HIGH-STRENGTH CHEMICAL RESISTANT ELASTOMERS FOR EXTREME TEMPERATURE SERVICE
Abstract
The synthesis of new fluorinated elastomers serviceable at low temperatures is described. Hexafluoroacetone and hydrogen-containing olefins have been found to form both low polymers and hydrogen-containing oxetanes on actinic irradiation. Evidence is presented to show that the intermediate is a biradical. A new elastomer system has been discovered involving the condensation of a polyfluorinated diol with a fluorocarbon diene. This unique fluorinated polyether has been found to have a very low transition temperature (-54 C). Evidence has also been found that a polyfluorinated diol will condense with hexafluorobenzene. Polyurethane polymers have been successfully formed by condensation of a polyfluorinated diol with phosphorous-containing diisocyanates. Several new monomers are described.
