METHODS AND COMPOSITIONS FOR INHIBITING VINYL AROMATIC MONOMER POLYMERIZATION
-
, (2013/03/26)
Methods and compositions are provided for inhibiting the polymerization of a vinyl aromatic monomer, such as styrene monomer, during elevated temperature processing thereof or during storage or shipment of polymer containing product. The compositions comprise a combination of a quinone methide derivative A) and a phenol compound B). The methods comprise adding from about 1-10,000 ppm of the combination to the monomer containing medium, per one million parts of the monomer.
Thioether substituted hydroxybenzophenones and stabilized compositions
-
, (2008/06/13)
2-Hydroxybenzophenone derivatives substituted in the 4′-position by a thioether moiety exhibit enhanced absorption in the UV at longer wavelength. Compositions comprising organic material subject to actinic degradation are beneficially stabilized with such derivatives.
Lubricant composition

, (2008/06/13)
A composition comprising a) a lubricant or a hydraulic fluid and b) at least one compound of the general formula I STR1 in which x=1 or 2 and, if x=1, R is as defined for R1 or R3 --O-- or, if x=2, R is as defined for R8, and R1 and R3 are, for example, alkyl, cycloalkyl, alkenyl, phenyl, naphthyl, aralkyl or alkaryl, or alkyl, cycloalkyl, alkenyl, phenyl, naphthyl, aralkyl or alkaryl, which are monosubstituted or polysubstituted by groups from the series comprising halogen, cyano, nitro, e.g. --OCH3 or e.g. --COOCH3, or alkyl, cycloalkyl, alkenyl, aralkyl or alkaryl which are interrupted by one or more groups from the series comprising --O--, --S--, --NH--, STR2 or alkyl, cycloalkyl, alkenyl, aralkyl or alkaryl which are monosubstituted or polysubstituted by groups from the series comprising halogen, cyano, nitro, e.g. --OCH3 or e.g. --COOCH3 and interrupted by one or more groups from the series comprising --O--, --S--, --NH--, STR3 and R2 is NR4 R5, --OR6 or --SR7, and R4 and R5 are identical or different and are, for example, --H, alkyl, phenyl, naphthyl, aralkyl or alkaryl, or R4 and R5, together with the N atom linking them, form, for example, a piperidine or morpholine radical, and R6 and R7 can be alkyl which may be interrupted by one or more groups from the series comprising --O--, --S--, --NH--, STR4 or are, for example, phenyl, naphthyl, alkaryl or aralkyl, and R8 can be alkylene which may be interrupted by at least one --O-- group or alkylidene which may be interrupted by at least one --O-- group. Some of the compounds of the formula I are novel. The compositions show an improved stability towards oxidative degradation, confer protection under extreme pressures and reduce frictional wear.
