A thermosetting plastic foam solid is obtained using a blowing agent comprised at least partially from depolymerization of dicyclopentadiene into essentially pure cyclopentane. This unique hydrocarbon is miscible in polyester polyols, where others, such as extracted cyclopentane, are not. In a blend of 15 parts of liquid flame retardant per hundred parts polyester polyol, the mixture is both stabl...

Error reporting may be enhanced by utilizing a programming language, such as C++ and its attendant enhanced error reporting facility. The invention generates an error message at the function level where the error occurs, as well as noting the line of source code during which time the error occurred. The resulting populated error message (82) is then rolled up toward the main program (20). At each ...

Plastisol compositions based on vinyl chloride/vinyl acetate copolymers produced by a suspension polymerisation process have a low viscosity even when the polymer/plastifier ratio is low, so that they can be made into airless spraying plastisol compositions. These compositions are storage stable and easy to gel. Coatings based on these plastisols have good sound-proofing properties even when their...

An absorbent material comprising a mixture of (1) a plurality of absorbent gelling particles comprising a water-insoluble, water-swellable polymer, and (2) an absorbent property modification polymer reactive with at least one component included in a urine. The mixture is made by (i) applying a solution containing an organic solvent, water and the absorbent property modification polymer onto the pl...

Measuring or sensing the downhole environment electrically, acoustically, mechanically, or by nuclear means, either the borehole fluid or surrounding subsurface strata is well stablished practice, However, the techniques or measuring the downhole environment and performing the hole finding function are currently mutually exclusive. To combine the abillity to measure or sense the downhole environme...

The invention relates to the use of polymeric foam materials for insulation. These polymeric foams are prepared by polymerization of certain water-in-oil emulsions having a relatively high ratio of water phase to oil phase, commonly known in the art as high internal phase emulsions, or "HIPEs". The HIPE-derived foam materials used in the present invention comprise a generally hydrophobic, flexible...
