Macromer stabiliser precursor for polymer polyols. |
摘要 |
Process for the preparation of a macramer suitable as a stabilizer precursor in a polymer polyol, which process comprises reacting a polyol with a cyclic dicarboxylic acid anhydride not containing any polymerizable double bond, and subsequently reacting the adduct thus obtained with an epoxide compound containing a polymerizable double bond. The macromers can be applied for the preparation of polymer polyols which are, in turn, very suitable for manufacturing flexible polyurethane foams. |
