Mechanistic r~atures of the cationic copolymerization of lactones with cyclic ethers are studied for fl-propiolactona ~ ?L) with tetrahydrofuran (THF) and E-caprolactone (CLI with THF. It is shown that, in the PL THF system at [THF]0 > [THF]~, the copolymer is considerably enriched with the more bas
By ring-opening copolymerization of 1,4-anhydr0-2,3-di-O-ethyl-~-erythritol (cis-3,4-diethoxyoxolane, 1) or 1,4:2,5:3,6-trianhydro-~-mannitol (3) with tetrahydrofuran carbohydratecontaining copolyether polyols were obtained. Using trifluoromethanesulfonic acid as catalyst the molecular weights were
