    摘要: An injection molding process for making a plastic article, the process comprising the steps of: A. Forming a moisture-curable composition comprising a 1. Silane-functionalized polyethylene, 2. Moisture source, e.g., a moisture-containing filler, wherein the moisture source excludes alcohols, and 3. Condensation catalyst; B. Injecting the composition into a mold; C. Subjecting the composition to conditions sufficient to 1. Release moisture from the moisture source, and 2. Partially cure the composition; D. Removing the partially cured composition from the mold; and E. Continuing the cure of the composition outside of the mold. The process is particularly well suited for the manufacture of thick parts, such as wire and cable elastomeric connectors.

    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.
