Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: Non-aqueous, polymeric reagent film compositions for use with analytical test devices of the dry chemistry type are described. The film compositions are prepared from an organic solution of a copolymer formed by interaction of at least two monomers wherein(a) the first monomer is a hydroxylated acrylate of the general formula ##STR1## where R1 is hydrogen or, more preferably, methyl, and R2 is a hydroxyalkyl group having from 1 to 5 carbon atoms, and(b) the second monomer is a neutral acrylate of the general formula ##STR2## where R1 is hydrogen or, more preferably, methyl, and R3 is a substituted or unsubstituted alkyl group having from 1 to 8 carbon atoms.Preferably, a third monomer is also included which is an amine-containing acrylate of the general formula ##STR3## where R1 is hydrogen or, more preferably, methyl, and R4 is a substituted or unsubstituted aminoalkyl or glycidyl group having from 1 to 5 carbon atoms or a surfactant polyethylene glycol group having from 10 to 30 carbon atoms.

Abstract: Inclusion of a stabilizer selected from phenyl and naphthyl esters of benzene and naphthalene carboxylic acids and mixtures thereof in an article, e.g. a photographic element, comprising an organic dye or precursor thereof increases stability of the dye against ultraviolet radiation. Particularly good results are achieved when the stabilizer is dispersed in a polymer of relatively high solubility parameter and low crystallinity.

Abstract: The invention is a process for making porous amine/aldehyde structures or powders comprising solid approximately-spherical cross-linked particles of less than 10 microns, said process comprising electrolyzing aqueous solutions of urea-formaldehyde prepolymer, melamine-formaldehyde prepolymer or mixtures thereof under electrolysis conditions sufficient to initiate condensation polymerization and formation of said structures or powders. The structures are all broadly designated as open pore urea-formaldehyde structures (OPUF) even though, of course, the ones made from melamine and formaldehyde without urea will have no urea in them. If the reactor is stirred during polymerization powders consisting of primary spherical particles and small porous agglomerates, are formed.
