TL;DR: In this article, a screw extruder is used to mix and extrude thermoplastic olefin elastomers, which have superior mechanical properties, thermal stability, processability and adhesiveness.
Abstract: A process for preparing thermoplastic olefin elastomers which comprises mixing and extruding in a screw extruder (A) an olefin rubber having a number average molecular weight of about 10,000 to 100,000 and composed of a copolymer of ethylene with an α-olefin containing at least 3 carbon atoms and (B) about 1 to 15 parts by weight, per 100 parts by weight of the olefin rubber (A), of a specified dicarboxylic acid monomer at about 200 to 320° C in the presence of (C) 0.02 to 3 milliequivalents, per 100 grams of the olefin rubber (A), of an alkyl peroxide, and in the absence of molecular oxygen. The thermoplastic olefin elastomers have superior mechanical properties, thermal stability, processability and adhesiveness, and find a wide range of applications, for example, as extrusion or injection molding materials, adhesives, coating agents, and modifiers for plastics and rubbers.

TL;DR: A BLEND of ASPHALTIC MATERIAL and PLASTOMERIC Materials, with or without POLYETHYLENE, in the form of an EPM or EPDM Plastomer in this article.
Abstract: A BLEND OF ASPHALTIC MATERIAL AND PLASTOMERIC MATERIAL, WITH OR WITHOUT POLYETHYLENE, IN WHICH THE PLASTOMERIC MATERIAL IS IN THE FORM OF AN EPM OR EPDM PLASTOMER IN WHICH ETHYLENE REPRESENTS 75-90 MOL PERCENT OF THE ETHYLENE-PROPYLENE CONTENT.

TL;DR: In this article, the effect of polymer modification on the flow behavior of bitumens was investigated and the results confirmed that the rheological properties of PMBs are strongly influenced by polymer nature and polymer content, confirming the applicability of the Cox-Merz relationship for plain bitumen and the PMBs with low polymer content.

TL;DR: In this paper, a modified asphalt composition is provided comprising an oxidized polyethylene, a styrene-butadiene-styrene block copolymer, and asphalt, as well as a hot mix asphalt composition.
Abstract: A modified asphalt composition is provided comprising at least one plastomer, at least one elastomer, and asphalt. More specifically, a modified asphalt composition is provided comprising an oxidized polyethylene, a styrene-butadiene-styrene block copolymer, and asphalt. A hot mix asphalt composition is also provided comprising the modified asphalt composition and aggregate. Processes for producing the modified asphalt composition and the hot mix asphalt composition is also provided as well as articles produced from these inventive compositions.
