    摘要: Scorch is inhibited during the free-radical crosslinking of a crosslinkable polymer, e.g., an EPDM, by incorporating into the polymer before melt processing and crosslinking a scorch inhibiting amount of a derivative, preferably an ether, ester or urethane derivative, of a TEMPO compound, e.g., 4-hydroxy-tetrahydrocarbylpiperidin-1-oxyl. The scorch inhibitors of this invention perform as well, if not better, than their 4-hydroxy-tetrahydrocarbylpiperidin-1-oxyl counterparts in similar polymer compositions and under similar conditions in terms of scorch inhibition and ultimate degree of crosslinking, but exhibit less volatility and less migration within the polymer composition.

    摘要: 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.
