    摘要: This invention relates to adhesives which are particularly useful in bonding polymeric materials used in the encapsulation and termination of insulated electrical conductors. The adhesive comprises a polar copolymer of an .alpha.-olefin, said copolymer preferably having an acid number in the range of from 4 to 40 and containing pendant ester, amide, ketonic, anhydride or carboxylic acid groups and an inorganic silicon-containing compound which has been chemically treated with an organosilicon compound.

    摘要: A filler system for polymers is disclosed which provides high voltage insulation which is resistant to tracking. The filler system utilizes a combination of alumina trihydrate and a chemically treated silica filler. The silica-treated filler results from the exposure of an inorganic silicon-containing filler having a specific surface area of at least 40 square meters per gram to one or more silanes. Preferred silanes are substituted silanes having the formula R.sub.n Si X.sub.4.sub.-n where n is 1, 2 or 3, R is an organic radical bonded to the silicon atom by a Si--C bond and X is a radical bound to the silicon atom via an atom other than a carbon atom.
