Monoepoxide-polyol adducts, and process for preparing the same.

摘要

An adduct of: a) one or more polyhydric alcohols of formula R(OH)n in which R or each R independently is an aliphatic or heterocyclic moiety of from 2 to 18 carbon atoms, the hydroxyl groups are attached to a primary carbon atom, or a secondary carbon atom with the proviso that there is a second hydroxyl group attached to a carbon atom no more than 4 carbon atoms away from said secondary carbon atom, and n or each n independently is an integer of from 2 to 6, and b) an at least equimolar amount of one or more monoepoxides of formula <CHEM> in which R min or each R min independently is an optionally substituted aromatic moiety of up to 14 carbon atoms, said adduct having a molecular weight distribution Mz/Mw of from 1 to 1.2.
