By ring‐opening copolymerization of 1,4‐anhydro‐2,3‐di‐ O ‐ethyl‐D‐erythritol ( cis ‐3,4‐diethoxyoxolane, 1 ) or 1,4:2,5:3,6‐trianhydro‐D‐mannitol ( 3 ) with tetrahydrofuran carbohydratecontaining copolyether polyols were obtained. Using trifluoromethanesulfonic acid as catalyst the molecular weights were in a range from M̄ w = 13 000 up to 25 000 with about 10% of carbohydrate constituent. The novel copolyethers were studied by polymer analytical procedures, their structures 4 and 5 tentatively assigned and compared to the homopolymerization products of the monomers. The present procedure features an approach to novel partially functionalized high molecular weight copolymer polyols based on carbohydrate‐derived materials.
