Summary: | The present invention relates to the synthesis of di(hydroxymethyl)tetrahydrofuran (DHMTHF) and the preparation of trans-enriched mixtures of DHMTHF. The invention further refers to polyester polyols which are obtained by reaction of cis/trans DHMTHF mixtures with a dicarboxylic acid. The invention further relates to polyurethanes and compositions containing a polyester polyol comprising DHMTHF, in particular to such polyurethane-containing (adhesive) compositions. |
