    摘要： This invention relates to two-component curable hot-melt compositions comprising thermoplastic polyamide resins that are substantially free of piperazine-containing polyamines. In one preferred embodiment the polyamide resins are the reaction product of an acid component with an amine component, wherein the amine component consists essentially of about (i) 20 to 100 equivalent percent of one or more acyclic diamines selected from the group consisting of 2-methyl-1,5-pentanediamine, 1,3-pentanediamine, 1,3-propanediamine, 1,5-pentanediamine, 1,7-heptanediamine, 1,9-nonanediamine, methyl-1,9-nonanediamine, 1,2-propanediamine, and 2-methyl-1,2-diaminopropane, and (ii) about 0 to 80 equivalent percent of one or more polyamines selected from the group consisting of cyclic and acyclic polyamines other than those amines of (i). The compositions possess excellent heat resistance, flexibility, elasticity and resistance to solvents, including organic solvents and water.

    摘要： This invention provides acrylate-modified polyamide resins comprising the Michael addition product of a mixture of a thermoplastic polyamide and reactive diluent with a polyol ester having a plurality of acrylate ester groups, wherein the mole ratio of the initial acrylate groups of the polyol ester to the initial amino groups of the polyamide ranges from about 0.5 to about 8.0, and wherein the reactive diluent's from about 1% to about 25% by weight polyamide. The diluent comprises mono- and di-substituted amines of 10 to 44 carbon atoms.

    摘要： Silicone rubber matrices are used to contain and dispense volatile, organic liquids. The articles, as dispensors are improved by the addition of a compatibilizing agent to reduce migration of the organic liquid out of the matrix in the form of liquid drops or films. Higher loadings of the organic liquid into the rubber matrix are achieved without syneresis occurring.

    摘要： Light-colored phenolic-modified rosin esters, suitable for use as, for example, tackifiers in adhesive compositions, are prepared by reacting together rosin, a phenolic compound, formaldehyde or a reactive equivalent thereof, and a non-phenolic hydroxyl-containing organic compound in the presence of at least one lightening agent selected from phenol sulfide compounds, phosphorous acid, esters of phosphorous acid, and hypophosphite salts. The formaldehyde or reactive equivalent is present in an amount ranging from about 1.1 to about 3.5 equivalents of --CHO moieties per 1 equivalent of Ar--OH moiety of the phenolic compound, in order to obtain rosin esters having desirably low color, and adequately low molecular weight to effectively function as tackifiers.
