Poly(ester sulfimides) Based on Dimethyl Ethers of Disaccharindicarboxylic Acids and Aliphatic Diols

摘要

New dimethyl ethers of disaccharindicarboxylic acids were prepared by reactions of methyl ether of saccharin-6-carboxylic acid and aliphatic alkylaryl-his(halides).The polycondensation of these diethers with glycols afforded poly(ester sulfimides) with aliphatic and aromatic groups showing solubility in organic solvents.According to DTA and TGA data,poly(ester sulfimides) are stable up to 310-340 deg C.
