    摘要: Polymer compositions comprise a (i) silane-functionalized polymer, e.g., a polyethylene grafted with vinyl triethoxy silane, (H) polyfunctional alcohol e.g., α,α,α′,α′˜tetramethyl-I,3-benzenediethanol and, optionally, (iii) acid, e.g., an alkylated aryl disulfonic acid. The use of polyfunctional alcohols in the absence of a strong acid yields a light-crosslinking of the silane-functionalized polymer and this, in turn, provides a polymer melt with improved extensional properties such as elongational viscosity and melt strength. The use of a polyfunctional alcohol in combination with a blocked strong acid provides a slow rate of crosslinking during melt processing and a high degree of ultimate crosslinking after the polymer composition has been shaped or molded.

    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.
