An asphalt composition includes asphalt, a non-epoxidized oil chosen from flux oils, bio oils, recycled motor oils, liquid plasticizers, and combinations thereof, and a polyolefin. The polyolefin has a weight average molecular weight (Mw) of from about 1,000 to about 20,000 g/mol, an optional acid number of from about 10 to about 50 mg KOH/g, an optional saponification number of from about 10 to about 100 mg KOH/g, and a density of from about 0.92 to about 1 g/cm. The asphalt composition has a performance grade of PG (52 to 88) and (&#x2212;22 to &#x2212;40), wherein (52 to 88) is an average seven day maximum pavement design temperature in degrees Celsius and represents deformation resistance and (&#x2212;22 to &#x2212;40) is an average one day minimum pavement design temperature in degrees Celsius and represents thermal cracking resistance, each as determined using AASHTO M320.

Methods for reducing asphalt pavement thickness are provided. A method for producing thin asphalt pavement includes combining a base asphalt, an oxidized polyolefin, and an aggregate to form an asphalt paving material. A layer of the asphalt paving material is deposited on a substrate layer and compacted to a thickness.

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&#xb0; 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.

A non-blown roofing grade bitumen composition comprising bitumen feedstock, polyolefin having a molecular weight of from about 800 to about 50,000 g/mol, and optionally one or more additives, wherein the softening point of the composition is above 70&#xb0; C. as determined according to method ASTM D36 and the penetration of the composition is at least about 12 dmm at 25&#xb0; C. as determined according to method ASTM D5. A method of making the same.

Asphalt compositions for roofing applications are provided, as well as filled asphalt material comprising the asphalt compositions and methods for making asphalt compositions and filled asphalt material. More particularly, the asphalt compositions comprise non-oxidized base asphalt; and a low molecular weight polyolefin present in an amount of from about 0.5 to about 15 wt % based on the total weight of the asphalt composition. The asphalt composition has a softening point from about 87.8 to about 160&#xb0; C. (about 190 to about 320&#xb0; F.), a penetration of greater than 12 deci-millimeters @ 25&#xb0; C., as well as improved stain resistance and heat resistance.

Hot melt adhesive compositions which have enhanced adhesion to difficult substrates, particularly at refrigerator/freezer temperatures or at elevated temperatures. The inventive compositions require a base polymer comprising an ethylene vinyl acetate-containing polymer; a tackifier; an adhesion promoting additive comprising at least one semi-crystalline polymer having a weight average molecular weight of about 30,000 daltons or less; and optional wax; and an optional antioxidant. It has been found that the adhesion promoting additive of this invention enhances the adhesion properties of a hot melt adhesive composition having ethylene vinyl acetate-containing polymer, particularly at elevated temperatures or at low refrigerator and freezer temperatures where other conventional adhesives have been unsuccessful.

Adhesion promotion to difficult substrates for hot melt adhesives

Asphalt binder compositions are provided comprising asphalt and a polymer blend, wherein the polymer blend comprises oxidized high density polyethylene and another polymer chosen from: maleated polypropylene, polyethylene homopolymer, high crystallinity polyethylene, and combinations thereof. Also provided are paving and roofing materials comprising the aforesaid asphalt binder compositions and an aggregate material. Methods for making and using the asphalt binder compositions are also provided.

Asphalt binder compositions and methods to make and use same

An asphalt paving material comprises an asphalt binder present in an amount of from about 3 to about 8 weight percent of the asphalt paving material. The asphalt binder comprises base asphalt and oxidized polyolefin that is present in an amount of from about 0.25 to about 10 weight percent of the base asphalt. Aggregate is present in an amount of about 92 to about 97 weight percent of the asphalt paving material. The oxidized polyolefin effectively adheres the asphalt binder to the aggregate so as to resist stripping of the asphalt binder from the aggregate caused by moisture.

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.

A process for selectively separating polyamides from multi-component waste materials including the steps of subjecting the multi-component mix to a specific mixture of caprolactam and water at a preselected temperature range below the degradation temperature of the polymer to be recovered, separating the formed polyamide solution, and recovering the desired polyamide. The process is very desirable for separating multi-component waste materials which contain not only nylon 6, but also nylon 6,6. The recovered polyamide may be used in molding applications and in fiber such as carpet fiber.

Selective polyamide recovery from multi-component materials

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.
