Multi-hydroxy-functional poly(propylene oxide) via random anionic copolymerisation

摘要

Polyether polyols are important materials, often used in the preparation of polyurethanes as a flexible, low glass transition temperature component. Polyether polyols with varied hydrophilicity or amphiphilicity can be prepared by copolymerising propylene oxide with other epoxides, and use of protected glycidols (eg ethoxy ethyl glycidyl ether with an acid labile acetal protecting group) can give more hydrophilic poly(propylene oxide)s.
