摘要

graft macromer, comprising the reaction product of at least one macromer that is at least one molecule comprising, in its structure, one or more hydroxyl-terminated polyester and / or polyether chains with at least one graft compound comprising , in its structure, a silyl group at least monoalkoxylated or at least monohalogenated and at least one group containing alkyl, cycloalkyl or aryl which is reactive to the hydroxyl group of the macromer, is used for dispersion, for example, of sio2 in polyol.
