  • Patent number: 5753749
    Abstract: Urethane-filled compositions are produced by reacting a dicyclohexylmethane diisocyanate residue or a dicyclohexylmethane diisocyanate residue containing mixture with a monofunctional alcohol containing at least one ether group in an amount such that the equivalent ratio isocyanate groups to hydroxyl groups is from about 0.9:1 to about 1:0.9. The diisocyanate residue or residue-containing mixture must contain at least 20% by weight monomeric diisocyanate and have a total NCO content of at least 10%. The diisocyanate residue is produced by phosgenating dicyclohexylmethane diamine in which less than 20% polymeric diamine is present. The urethane filled compositions produced in this manner may then be dissolved in either a polyol or a polyisocyanate and subsequently used to produce polyurethanes in known manner.

  • Patent number: 5710434
    Abstract: The invention is directed to a composition of matter useful as a paper impregnant, to the method of its use, and to the products produced by the method. Poly (diphenylmethane diisocyanate) or PMDI has been used in the past as a paper impregnant with or without propylene carbonate as a diluent. These products have generally required pressing under high pressures and at elevated temperatures. It has now been found that triacetin and/or triethyl citrate in usages up to about 20% of PMDI give superior performance in impregnated products. The modified PMDI will cure at essentially ambient conditions in times as short as 1-2 days to insoluble polyureas with low residual amounts of isocyanates and reaction byproducts such as 4,4'-diaminodiphenylmethane. The treated papers can be used in applications of which skins for sandwich panels and high strength corrugated board would be exemplary.

  • Patent number: 5506332
    Abstract: A process for preparing polyacetals by copolymerization of glyoxylic esters with other copolymerizable monomers in the presence of anionic or cationic polymerization initiators, with or without the introduction of stable end groups and with or without hydrolysis of the copolymerized units of glyoxylic ester present in the copolymer comprises using as monomers cyclic formals derived from diols, homopolymers of formaldehyde, trioxepane or mixtures thereof, although up to 50% by weight of this group of monomers may be replaced by other customary copolymerizable monomers, and the poly(acetal-carboxylate)s thus obtainable are useful as additives in reduced-phosphate and phosphate-free detergents and cleaners, as water treatment agents and as dispersants for finely divided substances.

  • Patent number: 5504145
    Abstract: Water dispersible, one component, self crosslinkable poly(urethane-urea) composition that is stable and capable of curing at room temperature is prepared by forming a prepolymer comprising an alcoholized drying oil; a diisocyanate, a polyalkylene ether polyol, and a dihydroxy containing alkanoic acid polyol; neutralizing the prepolymer; contacting the neutralized prepolymer with water and diamine wherein the alcoholized drying oil has a sufficient content of monoglycerides to allow for chain extension in step (C) and the poly(urethane-urea) self-crosslinks upon drying. The waterborne poly(urethane-urea) composition exhibits good chemical resistance, adhesion, abrasion, and high gloss properties when used as a coating.

  • Patent number: 5502096
    Abstract: A room temperature curable rubber composition of a condensation curing type that comprises as a base polymer a diorganopolysiloxane or a polyoxyalkylene in which both ends of the molecular chain are blocked with a hydrolyzable silyl group, and a carbonyl compound, an amino group containing organic compound, and an .alpha.,.beta.-unsaturated carbonyl compound that are blended with the base polymer. Since the room temperature curable rubber composition is cured with water in the air and at the same time the dehydration condensation of the carbonyl group and the amino group produces water in the composition, the quick curability and deep curability are improved remarkably.

  • Patent number: 5461137
    Abstract: A method for forming a homogeneous, concentrated, prepolymer composition, and a method of using the concentrated prepolymer composition to uniformly coat fibers is described. The prepolymer mixture is formed by dissolving a dialkyl, trialkyl, or tetraalkylester of biphenyltetracarboxylic acid in a solvent comprising ethyl acetate and methanol in a molar ratio of from about 1:3 to about 1:60, to form an ester solution. Diamine and end cap compound are added to the ester solution to form a monomer mixture solution. The end cap compound is a divalent compound characterized by (i) at least one unsaturated moiety, (ii) capable of reacting with the diamine or the ester to form an end cap radical that precludes further reaction of the diamine with the ester, and (iii) capable of undergoing addition polymerization. A portion of the solvent is evaporated from the monomer solution to form the substantially homogeneous, concentrated, prepolymer composition.

  • Patent number: 5447988
    Abstract: In accordance with the present invention, there is provided a novel composition for attaching a semiconductor device to a substrate. The invention composition comprises liquid polycyanate ester monomer, electrically conductive filler, and a curing catalyst, in the substantial absence of alkylphenol. The recognition that attach paste compositions are effective without the addition of alkylphenol has the benefit of reducing the cost of preparation, as well as the ease of preparation of die attach pastes containing electrically conductive filler and polycyanate ester monomer. The incorporation of alkylphenol into die-attach paste compositions has been found to be unnecessary, due to the presence of catalytically active species on the surface of filler flake employed in the preparation of such pastes.
