Polyetherester resins from diol diesters |
摘要 |
An improved process for making polyetherester resins is disclosed. The process comprises reacting a polyether with a diol diester in the presence of a catalyst that promotes random insertion of the diester into carbon-oxygen bonds of the polyether to produce the polyetherester resin. The process of the invention offers many advantages, including higher resin yields, reduced by-product generation, and the ability to make resins with low color and low acid numbers. The resins are useful for making polyetherester thermosets. |
