Laminates are provided of at least one polynorbornene prepreg comprising a substrate coated with a polynorbornene secured to a conductive surface, such as copper having an etched matte texture thereon. Adhesion between the polynorbornene prepreg and the conductive surface is improved by coating the conducting surface with as silane coupling agent and/or by providing polyolefin film therebetween. T...

A composition and method for reducing particulate emissions from a diesel engine without measurably increasing NOX emissions from the diesel engine comprises: 1) burning in the diesel engine in excess air a fuel oil containing 0.01 ppm to 1 ppm of iron in a compound selected from the group consisting of ferrocene and its derivatives represented by the formula: wherein each of R and R min ...

The invention is a process for the production of, substantially neutral, low-volatility organic compositions containing reactive olefinic double bonds, from starting materials which contain the compositions together with small quantities of acidic reaction constituents and/or corresponding auxiliaries, in the liquid phase by neutralization and separation of the salts formed. The neutralization is ...

A process for the production of (meth)acrylic acid esters of polyhydric alcohols by reaction of the reactants in the presence of acidic esterification catalysts with addition of polymerization inhibitors to the reaction mixture and purging of the reactor interior with an oxygen-containing gas stream. In the process part of the reactor interior filled with the gas phase is charged with finely divid...

Fuel briquets with a finely disperse carbon carrier of petroleum coke or of a mixture of mainly petroleum coke and coal (preferably non-caking coal) with a binder mixed with a finely disperse combustion inhibitor in the form of calcium carbonate and/or dolomite, which has been added in a quantity of more than 2% by weight to the starting mixture of the fuel briquet, volatile constituents having be...

The components forming the layers of a composite pipe are successively introduced into a rotary drum (1). Initially, a plastic reinforcing lyaer (8), including a fiber reinforcement, is introduced into the drum, the ends of the drum (1) being bounded by rings. A concrete core layer (16) is then introduced and the length of the core layer (16) is shortened relative to that of the drum (1) by shapin...

A cleaning, degreasing, antiadhesive liquid product composed of 95 DEG denatured alcohol and of a mixture of carbon-containing solvents. This mixture of solvents preferably comprises naphtha C, naphtha F and naphtha E: a preferred composition of the product comprises, by volume, 50% of alcohol, 5% of naphtha E, 15% of naphtha C and 30% of naphtha F.
