Abstract: The present disclosure relates to a fire retardant laminate and a fire-resistant wood product comprising the fire retardant laminate.

Abstract: An artificial turf filament comprising a polyolefin, a polyamide, a polyester, or a combination thereof, wherein the filament has a surface area, with at least a portion of the surface area being halogenated to form a halogenated surface

Abstract: The present invention is a continuous process for preparing formulations useful for making filled polymer carpet backings. The present invention particularly incorporates polyisocyanate as a reactive diluent in a continuous process for preparing filled polyurethane polymers. Use of the present invention allows production of carpet backings that incorporate high loadings of filler materials.

Abstract: A combination of a camera mount and a gun mount allowing horizontal, vertical and positional adjustment with manually activated locking knobs allowing comfortable multidirectional shooting with a gun that may be rigidly clamped in any one of a multiplicity of rapidly adjustable positions and with the camera adjustably mounted allowing a hunter to take a picture instead using the gun.

Abstract: Novel catalyst compositions comprising complexes of tin(IV) salts and amine compounds are used to prepare polyurethanes, polyureas, polycarbodiimides and polyisocyanurates. The complexes, which preferably employ primary amines, allow delay of gelation until they dissociate under certain reaction conditions. The complexes can be prepared neat or in situ in an active hydrogen containing formulation component. The complexes serve to delay gelation of the formulation because they can be prepared to be relatively stable to moisture and will predictably dissociate upon heating, either as a result of the exothermic nature of the reaction being catalyzed or with application of an external heat source. The catalyst compositions are particularly useful for preparation of carpet underlay and in other applications requiring significant delay prior to gelation.

Abstract: A polyurethane adhesive is prepared from a reaction mixture containing small amounts of chain extender material and a high equivalent weight of a polyol and a monoalcohol. An article adhered to a substrate using this adhesive is firmly affixed to the substrate, yet can be removed without leaving residual adhesive on the substrate. In addition, this adhesive can be washed and reused if desired.

Abstract: This invention is an active hydrogen-containing composition comprising a relatively high equivalent weight active hydrogen-containing material and an inert, particulate filler which is stabilized with a stabilizer composition comprising(1) a carboxylic or phosphorus-containing acid containing about 8 to about 30 carbon atoms and(2) a metal salt of a carboxylic acid containing about 8 to about 30 carbon atoms.The stabilizer composition substantially reduces the tendency of the filler to settle out of the relatively high equivalent weight active hydrogen-containing compound, while having minimal impact on the reactivity of the active hydrogen-containing composition with a polyisocyanate and on the physical properties of the resultant polyurethane.

Abstract: This invention is a polyurethane composition useful for backing textiles comprising the catalyzed reaction product of a polyurethane-forming composition which comprises:(A) a first polyol which comprises a relatively high equivalent weight polyol containing an average of about 1.4-1.95 hydroxyl groups per molecule, of which hydroxyl groups at least 30% are primary hydroxyls or a mixture thereof with at least one additional relatively high equivalent weight polyol containing at least 2.05 hydroxyl groups per molecule, of which at least 30% are primary hydroxyls;(B) a relatively low equivalent weight compound having about 2 active hydrogen containing moieties per molecule;(C) a polyisocyanate and(D) a catalytic amount of a catalyst for the reaction of a polyol and a polyisocyanate,wherein the functionalities and proportions of components (A), (B), and (C) are such that such components have an average functionality of about 1.97-2.03, and the composition has an isocyanate index of about 85 to about 125.

Abstract: Flexible polyurethane foams having improved flame resistance and "guide factor" are prepared by reacting a copolymer polyahl, isocyanate-terminated prepolymer containing a cotrimer of MDI and a blowing agent.

Abstract: Trimerized isocyanates having improved solubility in polyisocyanates are prepared by reacting a polyisocyanate with a low equivalent weight polyol to form a first prepolymer, forming a cotrimer from said first prepolymer by reaction of same with diphenylmethane diisocyanate or polymeric derivatives thereof, and forming a second isocyanate terminated prepolymer by reacting said cotrimer with a second low equivalent weight polyol. The resulting cotrimer can be diluted in a polyisocyanate and used to prepare polymers, particularly polyurethane foams, having excellent properties.
