A hydrocarbon mixture containing modified polycyclic aromatic compounds or modified PAC having a chemical structure of mean molecular weight ranging between 300 and 10,000, the chemical structure being represented by formula (I): (A)(PAC), wherein x and y are integers corresponding to the numbers of A or PAC units, selected such that x/y is equal to at least 1, preferably ranging between 1 and 50 and wherein A is a unit corresponding to a polymerizable monomer containing between 2 and 60 carbon atoms.

Hydrocarbon mixtures comprising modified polycyclic aromatic hydrocarbons

The invention concerns a composition comprising: (1) an asphaltene-free bituminous binder mixture, containing at least a plasticizing agent based on an aliphatic hydrocarbon compound, at least a structuring agent based on a cycloaliphatic hydrocarbon polymer and optionally a first polymer; (2) a coloured pigment; and (3) a second polymer selected among polyolefins, natural and synthetic rubbers and vinyl ethylene acetate copolymer.

Colored composition comprising a bituminous binder and uses thereof

An emulsion consists essentially of clear binders and possibly colored pigments, and contains at least one clear synthetic binder with a softening point or ball-ring temperature (TBA), measured according to the NFT 66-008 standard, that ranges between 30 and 100&deg; C., at least one compound from the latex family, introduced in a quantity that ranges between 3 and 40% by weight of the emulsion, water, and at least one emulsifying agent

Synthetic bitumen oil-water emulsions, their preparation and their applications

Bituminous compositions of the bitumen-polymer type, in homogenous phase, contain at least one bitumen base and are prepared from at least one polymer of the thermoplastic polyolefin type. These compositions have a thermoplastic polyolefin content of at least 1% by weight of which the crystallinity rate is greater than or equal to 30%, a melting temperature greater than or equal to 110.degree. C. and a penetrability at 25.degree. C. less than or equal to 300 tenths of a millimeter.

Bituminous compositions prepared from thermoplastic polyolefins and

A process for degrading thermoplastic polyolefins, in particular high or medium density polyethylenes, uses as a catalyst a mineral solid containing copper or a mineral solid containing aluminium and silicon and with an acid nature, at a temperature of 200.degree. C. to 450.degree. C., degradation being accompanied by incorporation of the degradation products into a heavy hydrocarbon such as a bitumen base. Incorporating degraded thermoplastic polyolefins, in particular degraded high or medium density polyethylenes, into heavy hydrocarbons can produce compositions with industrial and road applications.

Catalyzed degradation of thermoplastic polyolefins and incorporation of

A composite material comprising at least two elastomer layers, the first layer having a first composition comprising from 40 to 80 percent by weight of silicone rubber, the second layer having a second composition comprising from 50 to 100 percent by weight of rubber of the ethylene-propylene copolymer and/or terpolymer type, wherein the first composition further contains from 20 to 60 percent by weight of rubber of the ethylene-propylene copolymer and/or terpolymer type, and each of the two compositions contains more than 5 percent, and preferably from 5 to 60 percent, by weight of silica.

Composite material based on rubbers of the silicone type and of the

EPDM and/or EPR rubber/silicone compositions having improved thermal properties, well adapted for the production of a wide variety of useful shaped articles, e.g., automotive seals, gaskets and belts, include a 2-mercapto-benzimidazole or salt thereof, preferably the zinc salt, an antioxidant comprising a secondary amine function, a diorganopolysiloxane oil, appropriate filler material and a peroxide crosslinking catalyst.

EPDM and/or EPR rubber/silicone compositions

A continuous process for making rigid PVC foam objects by extruding a preform from an initial PVC mixture, optionally cutting the preform into blanks, and expanding the preform or the blanks in water heated to a temperature above 70.degree. C. The initial mixture contains polyvinyl chloride, at least a first blowing agent capable of generating a gas, for example an isocyanate or a polyisocyanate, and at least one organic anhydride (and does not contain any added inert particles finely divided therein). The initial mixture may also contain less than one weight percent of a second blowing agent, for example azobisisobutyronitrile or azodicarbonamide. The objects produced possess heat- and sound-insulating properties.
