An asphaltic compound according to the invention includes from about 70 to about 45 parts by weight of asphalt; from about 15 to about 25 parts by weight of a polymer modifier for said asphalt; from about 15 to about 25 parts by weight of a filler; and, from about 0.1 to about 5 parts by weight of a dispersing agent. The dispersing agent can be selected from the group consisting of stearic acid, tri(dioctyl) pyrophosphate titanate, tri(dioctyl) pyrophosphate-O, neoalkoxy tridodecylbenzenesulfonyl titanate, lecithin, aluminum stearate, maleic anhydride-modified ethylene/alpha-olefin copolymer, maleic anhydride grafted propylene-ethylene copolymer, ethoxylated alcohol, and mixtures thereof.

A flame retardant asphalt material useful for the processing and formation of a roofing membrane includes from about 40 to about 50 parts by weight of asphalt; from about 10 to about 20 parts by weight of a copolymer; from 0 to about 5 parts by weight of polypropylene homopolymer having at least about 45 percent by weight of crystallinity; from about 10 to about 40 parts by weight of a functional filler having a decomposition temperature above the processing temperature of the material; from about 0 to about 15 parts by weight of a non-functional filler; and, from about 0.5 to about 10 parts by weight of an intumescent material.

Flame retardant modified asphalt-based material and products therefrom

An asphalt material, useful for forming a membrane, comprises a mixture of from about 47 to about 74 parts by weight of asphalt, from about 7 to about 15 parts by weight of styrene-butadiene-styrene block copolymer, from about 15 to about 25 parts by weight of a filler component, and from about 1 to about 5 parts by weight of polypropylene homopolymer. A method for preparing a modified-asphalt material comprises the steps of forming a mixture by admixing from about 47 to about 74 parts by weight of asphalt; from about 7 to about 15 parts by weight of a styrene-butadiene-styrene block copolymer; from about 15 to about 25 parts by weight of a filler; and from about 1 to about 5 parts by weight of a polypropylene homopolymer; wherein the polypropylene homopolymer inhibits high temperature crosslinking of the styrene-butadiene-styrene block copolymer.

Described are control reagents useful in analyte determination. The reagents contain a known concentration or amount of the analyte to be assayed, and a polymer. The polymer is made up of monomers of either water soluble acrylic monomers, water soluble quaternary amines, or mixtures of these two types of molecules. Various control reagent formulations, as well as new polymers useful in control reagents, are disclosed.

The invention relates to a non-serum based control reagent for glucose determination. Rather than using modified serum, the control reagent contains water, glucose, and the viscosity agent polystyrene sulphonate. The control reagent may also contain a buffer, preservatives, surfactants or surface active agents. A method of making the control reagent is also disclosed.
