Preparation of polyethoxylates from solid polyols by reaction of a polyol and trimethylolpropane with a gaseous alkylene oxide

摘要

Composition, liquid at normal temperature and pressure, comprising a mixture of a polyoxylated polyol and polyoxylated trimethylolpropane, obtained by a reaction at less than 10 bars and 180[deg]C or less of a mixture of more than 50% wt. of a polyol of melting point greater than 180[deg]C, preferably greater than 200[deg]C, and less than 50% of trimethylolpropane (TMP), with an alkylene oxide, gaseous at ambient temperature and pressure. An independent claim is also included for the preparation of the liquid composition and of acrylic or methacrylic esters using the composition.
