    摘要： Thermoset elastomer compositions are disclosed. Such elastomers are the reaction product of (a) an ambient temperature liquid epoxy-terminated prepolymer formed by reacting a polyoxyalkyleneamine having a molecular weight of from 3000 to 20,000 with an excess of epoxide, wherein the polyoxyalkyleneamine has at least 3 active hydrogen atoms and (b) a curing agent comprising at least one amine or polyamine having an equivalent weight of less than 200 and having 2 to 5 active hydrogen atoms. Such elastomers can be used in applications such as for sealants, adhesives, coatings, gaskets, jointing and cast elastomers.

    摘要： Embodiments of the invention provide for methods of producing a composition comprising a crosslinkable silane-terminated polymer having at least one crosslinkable silyl group in each molecule. The method comprises providing a polymer having at least one unsaturated group and at least one alcoholic hydroxyl group in each molecule, adding to the polymer a compound having a hydrogen-silicon bond and a crosslinkable silyl group in each molecule and a hydrosilylation catalyst to thereby carry out a hydrosilylation reaction to form a composition comprising hydrosilylated polyoxyalkylene polymers, reacting the hydrosilylated polyoxyalkylene polymers with at least one isocyanate in the presence of a first tin-free catalyst to form an isocyanate reacted hydrosilylated polymer, and optionally reacting the isocyanate reacted hydrosilylated polymer with a polyol having a nominal functionality of at least 2 to form a polyol reacted crosslinkable silane-terminated polymer.
