OLUBILITY, ORGANIC PHOSPHORUS COMPOUNDS, CROSSLINKING(CHEMISTRY), MECHANICAL PROPERTIES, COPOLYMERIZATION, TRANSITION TEMPERATURE, NUCLEAR MAGNETIC RESONANCECHEMICAL ATTACK(DEGRADATION), RESISTANCE, SOLVENT RESISTANCE, FLUORINATED POLYMERS, COPOLYMERSLarge scale preparations of the ((CF3CH2O)2PN-(HCF2C3F6CH2O)2PN)n elastomer and the ((C3F7CH2O)2PN)n plastic are described. Limited compounding and processing studies for these materials are described. In an effort to alter vulcanizate properties, two elastomeric terpolymers, one containing (H2C=CHC2H4O)xPN and the other containing (CH3CH(OH)C2H4O)xPN, were prepared and two different synthetic routes were employed. Several process studies and exploratory syntheses were undertaken. The influence of water on the formation of ((CF3CH2O)2PN-(HCF2C3F6CH2O)2PN)n was investigated. The formation of this polymer by sequential addition of the fluoroalkoxides to the (Cl2PN)n solution also was studied. A ((CF3CHFCF2CH2O)2PN)n plastic and a ((CF3CH2O)2PN-(CF3CHFCF2CH2O)2PN)n elastomer were prepared. (Modified author abstract)
