    Abstract: 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.

    Abstract: An electronic device module comprising: A. At least one electronic device, e.g., a solar cell, and B. A polymeric material in intimate contact with at least one surface of the electronic device, the polymeric material comprising (1) a polyolefin copolymer with at least one of (a) a density of less than about 0.90 g/cc, (b) a 2% secant modulus of less than about 150 megaPascal (mPa) as measured by ASTM D-882-02), (c) a melt point of less than about 95C, (d) an a-olefin content of at least about 15 and less than about 50 wt% based on the weight of the polymer, (e) a Tg of less than about -35C, and (f) a SCBDI of at least about 50, (2) optionally, free radical initiator, e.g., a peroxide or azo compound, or a photoinitiator, e.g., benzophenone, and (3) optionally, a co-agent. Typically, the polyolefin copolymer is an ethylene/a-olefin copolymer. Optionally, the polymeric material can further comprise a vinyl silane and/or a scorch inhibitor, and the copolymer can remain uncrosslinked or be crosslinked.

    Abstract: Foamed articles are prepared from a composition comprising a low MI polymer, e.g., an ethylene/alpha-olefin copolymer with a density of less than 0,91 g/cc and an MI of less than 3 g/10 min, a chemical blowing agent, e.g., azodicarbonamide, a scorch inhibitor, e.g, a TEMPO compound, and, optionally, a free radical initiator, e.g., peroxide. If the composition does not comprise a free radical initiator, then it is exposed to a source of free radicals before and/or during the foaming process, e.g., e-beam or UV-light. The composition is compounded and foamed using conventional process equipment and conditions.
