摘要： This invention provides an alkoxylation process for creating alkoxylating chain extension of phenolic compounds by reacting phenolic compounds with alkylene glycol and urea in the presence of suitable catalysts to obtain alkoxylated compounds, which may be used as polymer intermediates, especially for use as raw materials to synthesize polyurethane (PU) or polyester.

摘要翻译： 本发明提供烷氧基化方法，用于通过在合适的催化剂存在下使酚类化合物与亚烷基二醇和脲反应来制备酚类化合物的烷氧基化链延伸，以获得烷氧基化化合物，其可用作聚合物中间体，特别是用作合成原料聚氨酯（PU）或聚酯。
