Abstract

The invention provides glycosyl polyethers, a preparation method thereof and use thereof. In the method, macromolecular glycosyl polyethers which have a molecular weight ranging from several hundred to more than 100,000 and have a structure below are prepared by starting from common glycosyl donors and by a method of using the glycosyls as starting ends, bonding the glycosyls with the open-loop long chains of alkylene oxide at anomeric positions and using common nucleopilic reagents such as hydroxys, alkoxys, aminos, nitrines and halogen atoms as capping ends. As the mechanical performance and plasticity of the glycosyl polyether compounds can be controlled conveniently by regulating the length of the polyether chain, the glycosyl polyether compounds can be used as medical materials, important materials for synthesizing polyurethane, thermoplastic polyester-polyamide elastic materials and precursors for preparing glyconanoparticles.

Description

technical field

[0001] The present invention relates to the preparation method, product and application of glycosyl polyether induced by glycosyl oxygen ions. technical background

[0002] Polytetramethylene glycol (PTMEG) prepared by cationic ring-opening polymerization of cyclic ethers such as tetrahydrofuran (THF) is an important raw material for the synthesis of polyurethane and thermoplastic polyester polyamide elastic materials. Compared with elastic materials produced by other materials as blocks, elastic materials made of PTMEG have excellent hydrolytic stability, air permeability and wear resistance, and also have good elasticity, flexibility and impact resistance at low temperatures It has unique and broad application prospects in textiles, pipes, chemicals and medical equipment. And polypropylene oxide is widely used in aspects such as polyurethane industry and surfactant [(a) Liu Zhihao, Sun Jingwu, polytetrahydrofuran synthetic catalyst research progress, 1999,...
