摘要

Manufacturing epoxy resin involves reacting epichlorohydrin with at least one aromatic polyol to obtain the epoxy resin and its salt, and in which use is made of at least one non-halogenated, non-aromatic alcohol, as an additive, added to at least one step of the process or formed in at least one step of the process, in an additional amount relative to the amount of non-halogenated, non-aromatic alcohol possibly present as an impurity in the epichlorohydrin and/or in the aromatic polyol.
