Evaluation of Poly(Fluoroalkoxyphosphazene) Elastomers and Plastics.
Abstract
The successful preparation of ((CF3CH2O)2PN)n, ((CF3CH2O)2PN-(2-CH3O-4-C3H5C6H3O)xPN)n, and ((C3F7CH2O)2PN)n plastics and ((CF3CH2O)2PN-(HCF2C3F6CH2O)2PN)n, ((CF3CH2O)2PN-(HCF2C3F6CH2O)2PN-(2-CH3O-4-C3H5C6H3O)xPN)n, ((HCF2CF2CF2O)2PN-(HCF2C3F6CH20)2PN)n elastomers are described. Compounding studies of ((CF3CH2O)2PN-(HCF2C3F6CH2O)2PN)n 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 poly(fluoroalkoxyphosphazene) 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)
