Abstract
Nitro-isopropenyldiphenyl ethers are provided which can serve as a useful source of known monomer intermediates or as intermediates for the preparation of nitro-haloisopropyl substituted diphenyl ethers. The latter have been discovered to act as facile alkylating agents with phenols providing nitro-p-hydroxyphenylisopropyl substituted diphenyl ethers. When the latter compounds are reduced there are obtained the corresponding amino-p-hydroxyphenylisopropyl substituted diphenyl ethers. The polymerization of this last class of compounds with acid halides provides polyamide-esters. The polymers can be used in the manufacture of such articles as tubing, hose, bellows hose, and the like.
