Abstract
A composition and method of making an improved sealant is disclosed. The sealant is made from a base polymer material that includes one or more substantially linear vinyl, acrylate, or methacrylate monomers, a hydrolyzable silane that includes one or more substantially linear vinyl, acrylate, or methacrylate silanes to produce randomly dispersed silane functionality throughout the polymer and a second hydrolyzable mercapto silane to cap some polymer chains via a chain transfer reaction, wherein the polymer has a glass transition point lower than 10° Fahrenheit and an average molecular weight between about 40,000 and about 500,000. A sealant is made by adding a cross-linking catalyst and other additives to the polymer in such proportions to produce a sealant that cures upon exposure to atmospheric moisture.
