Abstract: Plastomer-modified asphalt binders meeting MSCR specifications, asphalt paving materials with such asphalt binders, and methods for fabricating such asphalt binders are provided. The asphalt binder contains a base asphalt and a plastomer. If the plastomer has a drop point no greater than about 139° C., the asphalt binder further contains sulfur; sulfur-containing compounds, such as hydrocarbyl polysulfides and thiuram disulfides; phenolic resins; metal oxides; or a combination thereof. The asphalt binder is substantially free of elastomer.

Abstract: Disclosed are methods for advantageously producing maleated polypropylenes having a relatively high percentage of bound maleic anhydride, based on the total amount of maleic anhydride moieties present in the grafting reaction product, and the maleated polypropylenes produced therefrom. The methods produce maleated polypropylenes wherein at least about 60% of the maleic anhydride moieties in the grafting reaction product are bound to the polypropylene.

Abstract: This invention relates to a process of extracting a first spinning solvent such as mineral oil from a solution spun polymer fiber such as polyethylene through use of an extraction solvent such as dimethyl diethylene glycol and diethyl diethylene glycol in which the spinning solvent is soluble, which extracting solvent is soluble in a third extraction solvent such as water to a greater extent than the extraction solvent is soluble in the spinning solvent, such that the second extracting solvent can be extracted from a solution of said spinning solvent and said second extraction solvent by said third extracting solvent.
