PHYSICAL AND RHEOLOGICAL PROPERTIES OF NITROSO RUBBERS

Abstract

Characterization of a trifluoronitrosomethane/tetrafluoroethylene copolymer was continued. The CF3NO/C2F4 copolymer was found to be adaptable to elution fractionation in a perfluorocyclic ether and a benzotrifluoride system, even though 85% of the polymer eluted in a narrow viscosity range of 1.3 to 2.0. Values of K and K' of the copolymer in FC-75 were confirmed to be 0.353 and 0.147, respectively. Thermal decomposition in air and in an inert gas was shown to be identical. The glass transition of the copolymer, as measured by DTA, is in the region of -41 deg C to -46 deg C with no more than 2 deg C difference between production lots. The white insoluble material present in the production lots was identified to be basic magnesium carbonate trihydrate.
