    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： 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.
