Abstract:

The successful preparation of CF3CH2O2PNn, CF3CH2O2PN-2-CH3O-4-C3H5C6H3OxPNn, and C3F7CH2O2PNn plastics and CF3CH2O2PN-HCF2C3F6CH2O2PNn, CF3CH2O2PN-HCF2C3F6CH2O2PN-2-CH3O-4-C3H5C6H3OxPNn, HCF2CF2CF2O2PN-HCF2C3F6CH202PNn elastomers are described. Compounding studies of CF3CH2O2PN-HCF2C3F6CH2O2PNn copolymers and terpolymers demonstrated that good to excellent tensile strengths, good elongation, and compression set values could be obtained. The 2-CH3O-4-C3H5C6H3O group was introduced into several polymers in an effort to achieve better vulcanizate properties. Qualitative studies of several polyfluoroalkoxyphosphazene plastics to determine processability, mechanical properties, and thermal resistance are described. Weatherometer aging of a compounded vulcanizate had little or no effect on physical properties after 120 hours. Modified author abstract
