| Novel condensation polymers have been prepared by the copolymerization of a N,N*-disubstituted disulfonamide with an organic acid dihalide such as dicarboxylic dichloride,disulfonic acid dichlorides, bic chloroformates, phosgene, diisocyanates, etc,. Novel diepoxides have been prepared as follows: (1) the Claison rearrangement of allyl aryl ethers to allylphenols, (2) conversion of the allylphenols to allyl phenyl ethers and (3) epoxidation of the allyl phenyl ethers to diepoxides. An alternative and novel route transforms the N,N*-disubstituted disulfonamides to N,N*-disubstituted disulfonamides diepoxides via either epichlorhydrin technology or allylation followed by olefin epoxidation.Pending Application- Diepoxide Derivatives N*-Disubstituted Disulfonamidessee US 153 925 preparation disulfonamides) conversion N- disubstituted transformed diepoxides utilization either epichlorohydrin |
