A new class of organochromium compounds are described, namely, tetravalent chromium compounds having the formula Y.sub.4 Cr where Y is alkyl, cyclohexyl-substituted alkyl or phenyl-substituted alkyl. Typical compounds are tetra(neopentyl)chromium, tetra(cyclohexylmethyl)chromium and tetra(neophyl)ch ...

Reid Donald E: Stabilized polyolefins useful as wire insulation in petroleum-jelly filled cables. Hercules Incorporated, Rice Edith A, Dafter Jr Edwin H, February 4, 1975: US3864431 (3 worldwide citation)

Polyolefins useful for insulating wire for use in petroleum jelly-filled cables are stabilized by a combination of additives including a phenolic antioxidant, a polymeric ester of a thiodialkanoic acid and an inhibitor against copper induced degradation.

Breslow David S: Polyfunctional quaternary amidoximidinium salts. Hercules Incorporated, Staves Marion C, Whitson John W, Dafter Jr Edwin H, October 7, 1975: US3910929 (1 worldwide citation)

The invention relates to polyfunctional quaternary amidoximidinium salts. These salts are precursors to polyfunctional nitrile N-oxides and, as such, are useful in the modification of ethylenically unsaturated polymers. Representative of these salts is terephthalo-bis(hydroximoyl pyridinium chloride ...
