摘要： Molding compounds in various forms for molding into high performance composites, are prepared from reinforcing mica platelets, preferably of high aspect ratio, and thermosetting unsaturated polyester resins. The unsaturated polyester solid and a solid vinylic monomer are blended, finely divided (e.g. to about -200 mesh), and the platelets are uniformly coated with these fine particles by dry blending. A compaction with partial coalescence of the fine resin particles in situ is carried out to densify and aggregate the coated platelets and shape the mixture. The resulting molding powders, bulk or sheet molding compounds are readily molded into the high performance composites, the platelets being substantially protected from degradation by the distributed resin.

摘要： Chrysotile asbestos is chemically opened into the individual fibrils by soluble vinylic polymer polyelectrolytes containing carboxylic acid groups in aqueous media. Polyacrylic acids, polymethacrylic acids, maleic anhydride polymers and water-soluble copolymers thereof are preferred polyelectrolytes and form stable colloidal dispersions. The polyelectrolytes are neutralized to alkaline pH with inorganic or organic bases, but preferably with basic vinylic monomers when complete encapsulation is desired. By a further aspect of the invention the polyelectrolyte-coated fibrils in aqueous dispersion are encapsulated by copolymerization with (a) a basic vinylic comonomer (used for pH control) such as dimethylaminoethyl methacrylate, t-butylaminoethyl methacrylate or a vinylpyridine; and (b) a non-basic vinylic comonomer such as styrene, divinylbenzene, vinyl chloride or fluoride, vinyl acetate, methyl methacrylate, ethyl acrylate, acrylonitrile, and methacrylonitrile. The encapsulated fibrils are advantageous for forming reinforced composites including laminates and foamed or cellular products.

摘要： A process for producing a high modulus article includes forcing a high molecular weight plastic material, such as polyethylene, through a passage of which the cross-sectional area diminishes in the forward direction of plastic flow, thus producing an extrudate. The plastic material is extruded while it is close to or at its melt temperature, and it is lubricated to obtain substantially plug flow through the passage. The speed at which the plastic material flows through the passage is adjusted so that the elongational velocity gradient at any longitudinal position within the passage does not exceed about 2.6 sec..sup.-1, thus minimizing the degree of molecular orientation in the extrudate. The extrudate can be deformed by drawing while it is maintained at or close to its melt temperature, thus producing an oriented, deformed extrudate. The oriented extrudate is then quickly cooled to preserve the orientation. A suitable plastic material is high molecular weight polyethylene with an average molecular weight lying between about 500,000 and about 1,500,000.

摘要： The present invention provides a procedure for at least partial dissociation of crumb rubber vulcanate network, including automobile tires, and for the incorporation of this treated rubber into stable bitumen compositions. The at least partially dissociated rubber vulcanate network may be used independently as a bitumen modifier, or a stabilizing agent for ground vulcanate rubber dispersions in bitumen or as a steric stabilizer in dispersion of polyolefins in bitumen. The at least partially dissociated rubber vulcanate network materials are produced in situ in bitumen or produced separately and subsequently incorporated into bitumen and the bituminous compositions are useful materials for a variety of applications. Modifications are possible within the scope of this invention.

摘要： Bitumen-polyolefin compositions, e.g. for use as binders in paving compositions, are stabilized by an emulsifier system comprising a polyethylene wax terminally functionalized with acidic groups and having a polymeric main chain structure which is compatible with the polyolefin of the dispersed phase of the binder. In a preferred embodiment, the emulsifier system also includes an inorganic metal compound which will react chemically with the terminal functional groups of the polyethylene wax. Especially preferred is maleated polyethylene wax (as the polyethylene wax) and ferric oxide (as the inorganic metal compound). The emulsifier system forms a sheath of inorganic material around the dispersed polyolefin droplets, to stabilize them and to hinder their floatation to the surface of the binder composition.

摘要： Two or more different polymeric materials are stably incorporated into bitumen by effecting steric stabilization of a polyolefin, such as polyethylene, and by dispersing the other polymer, such as a styrene-butadiene-styrene copolymer, an ethylene-vinyl acetate copolymer or an EPDM copolymer in the stabilized polyethylene-bitumen composition. The ability to incorporate different polymeric materials in bitumen permits desirable modifications to the properties of the composition to be effected. In addition, different properties can be attained by modifying processing parameters.
