<p>Ethylene-vinylsilane copolymers are moisture-cured under ambient conditions using a synergistic combination of at least one Lewis acid and at least one Brønsted acid or at least one Lewis base and at least one Brønsted base. Preferably the catalyst system comprises a Lewis acid, e.g., dibutyltin dilaurate, in combination with a Brønsted acid, e.g., sulfonic acid. The Lewis acid or base and the Brønsted acid or base is present in the catalyst system at a molar ratio of Lewis acid/base to Brønsted acid/base of 1:10 to 10:1.</p> |
