Telomers

摘要

Phosphonic telomer intermediates for preparing the telomers of U.S. Pat. No. 5,376,731 may be produced by an aqueous process comprising (a) reacting hypophosphorous acid with a carbonyl compound which is preferably an aldehyde, a ketone or an imine, and (b) reacting the product of (a) with an olefinic reactant or reactants in the presence of a suitable initiator especially a free radical initiator. The telomer intermediates are themselves useful as scale inhibitors in aqueous systems.
