Facile synthesis of formaldehyde‐based polyether(‐carbonate) polyols

Abstract

Paraformaldehyde (pFA) was utilized as an abundant building block to synthesize remarkably stable liquid pFA-poly(alkoxy) and pFA-poly(alkoxy)(carbonate) triblock polyols by graft oligomerization of epoxides and variable amounts of CO2. The resulting tailor-made oligo diols are highly interesting precursors. They are partially made from alternative feedstock and are well suited as starting materials for state-of-the-art polyurethane chemistry. Moreover, this study demonstrates the general feasibility of a novel polyether polyol process with a significantly reduced epoxide demand.
