Abstract: A filler reinforced composite comprising bitumen as a continuous phase and as reinforcement in the bitumen, fillers which have been coated with a chemically-modified bitumen composition prepared by reacting a bituminous material with an organo metallic compound.

Abstract: A chemically-modified bitumen composition prepared by reacting a bituminous material with a chromium complex. The composition can be used to coat fillers and glass fibers, either in the form of individual filaments or bundles of glass fibers. The coated fillers and fibers can be used as reinforcement for bitumen or bitumen plus aggregate to securely tie the filler or glass fiber surfaces to the bitumen.

Abstract: Glass fibers, either in the form of individual filaments or bundles or glass fibers, which have been coated with a chemically-modified asphalt prepared by reacting a bituminous material with an organo silicon compound in which the organic group attached to the silicon atom contains a functional group reactive with the bitumen. The coated fibers can be used as reinforcement for bitumen or bitumen plus aggregate to securely tie the glass fiber surfaces to the bitumen.

Abstract: A bitumen composition modified with an organo silane in which a bitumen such as asphalt is reacted with an organo silane containing ethylenic unsaturation or an organo silane containing at least one hydrogen atom bonded to the silicon atoms whereby the organo silanes react with ethylenic unsaturation of the bitumen to chemically bond the organo silane to the bitumen. Also included are bitumens which have been chemically modified by reaction with steam, air, ammonia or aliphatic amines which have been reacted with a silane containing a functional group reactive with the bitumen. Bitumen compositions of the invention are preferably used in the treatment of glass fibers for use as reinforcement in asphalt systems.

Abstract: A rubber modified asphalt composition prepared by reacting a bituminous material with a polymerizable aromatic monomer and a rubbery polymer whereby the rubbery polymer is chemically integrated with the asphalt. The rubber modified asphalt compositions of this invention can be used in the treatment of glass fibers as well as in road paving applications, roofing applications and the like.

Abstract: The use of flake glass in road pavement and repair is disclosed. In particular, we disclose improvements in the formulations of asphalt aggregate wear surfaces, substrate layers and interface layers between the substrate and wear surfaces. In one embodiment we also employ an unsaturated monomer or an unsaturated elastomer.

Abstract: Chemically modified asphalt compositions prepared by reaction of asphalt with ammonia, a polyamine or an aromatic diamine. The chemically modified asphalt compositions of this invention are particularly well suited for use in the treatment of glass fibers as reinforcement for asphalt matrices.

Abstract: A thermoplastic composition produced by the polymerization of a monomer with unsaturated elastomeric polymers is disclosed. The composition is effective in improving the shrink and gloss of molded thermosetting resin compounds by blending therein.

Abstract: A thermosetting additive comprising, in its preferred form, the 2-hydroxyethyl acrylate adduct of poly(styrene-co-maleic anhydride), is blended with polyester-based thermosetting resins to produce molding compounds having improved surface characteristics.

Abstract: Thermoplastic additives comprising the esterification product of a polyol with dimer and trimer acids are blended with thermosetting resins to reduce the shrinkage of the latter on molding.

Abstract: Thermoplastic additives comprising the esterification product of a mixture of glycols and oligomers with dimer and trimer acids are blended with thermosetting resins to reduce the shrinkage of the latter on molding.

Abstract: The surface characteristics, including shrink and gloss of molded thermosetting resin compounds, are improved by incorporating into the thermosetting resin a thermoplastic composition produced by the polymerization of a monomer with unsaturated elastomeric polymers.

Abstract: A composition for use in the treatment of glass fibers to promote a strong bonding relationship between glass fibers and plastics and elastomeric materials comprising a silanized butadiene polymer which has been reacted with a halosilane and the product reacted with an epoxide to replace the halogen groups of the silane with beta-haloalkoxy groups.
