Synthesis of New Low Temperature Petroleum-Resistant Elastomers.
Abstract
Three petroleum resistant elastomers which are suitable for low temperature use have been prepared. The ( (CF3CH2O)2PN-(C3F7CH2O)2PN)n copolymer is very inert chemically, and is soluble only in selected fluorocarbon solvents. The material does not burn in air in a direct flame. The copolymers, ( (CF3CH2O)2PN-(HCF2CF2CH2O)2PN)n and ( (HCF2CF2CH2O)2PN-(HCF2C5F10CH2O)2PN)n, are highly elastic and are unaffected by hydrocarbons and benzene, but are soluble in many polar organic solvents. Process studies on the polymerization and derivatization are reported. (Author)
