Thioether-modified sealant compositions and insulated glass articles sealed therewith

Abstract

A cured window sealant formulation comprising a partially saturated alkanethiol adduct of an unsaturated polymer is disclosed. The alkanethiol has from 8 to 20 carbon atoms. The curing agent is a polyisocyanate, a polyol, a polyepoxide, a cyclic anhydride or any mixture thereof. The unsaturated polymer may be polybutadiene or polyisoprene. The window sealant exhibits good thermal stability, low water vapour transmission rate, non-sulfurous odour, low volatility, and acceptable elongation.
