Both the viscosity of a plastisol comprising a dispersed polymer, a plasticizer for the polymers and at least one liquid diluent, and exudation of liquids from articles formed from the plastisol are minimized when the difference between 1) the weighted average of the Hildebrand solubility parameter values of all liquid ingredients, including plasticizer, in the plastisol and 2) the Hildebrand solubility parameter of the dispersed polymer is ±0.6 to ±1. The plastisols of the present invention are suitable for fabrication into films and molded objects, and as coating materials for a variety of metallic and non-metallic substrates.

摘要:
Elastomer composites are produced by novel continuous flow methods and apparatus in which fluid streams of particulate filler and elastomer latex are fed to the mixing zone of a coagulum reactor to form a mixture in semi-confined flow continuously from the mixing zone through a coagulum zone to a discharge end of the reactor. The particulate filler fluid is fed under high pressure to the mixing zone, such as to form a jet stream to entrain elastomer latex fluid sufficiently energetically to substantially completely coagulate the elastomer with the particulate filler prior to the discharge end. Highly efficient and effective elastomer coagulation is achieved without the need for a coagulation step involving exposure to acid or salt solution or the like. Novel elastomer composites are produced. Such novel elastomer composites may be cured or uncured, and combine material properties, such as choice of filler, elastomer, level of filler loading, and macro-dispersion, not previously achieved.
摘要:
The present invention is directed toward a method for making a polymer that has nanostructures incorporated into the matrix of the polymer. The method of the invention involves the following steps: mixing a precursor solution for the polymer with a precursor for the nanostructures to form a mixture; forming nanostructures in the mixture from the precursor of the nanostructures; and forming a polymer from the precursor solution of the polymer so that the nanostructures are incorporated into the polymer matrix.
摘要:
A method of making a polymeric nanocomposite material. The method includes combining nanosize materials, such as layered silicates, or nanosize sphered silica, with a polymer and a solvent to form a substantially homogeneous mixture, followed by removal of the solvent. The method forms a layered-silicate nanocomposite with an intercalated nanostructure with very large interplanar spacing or a combination of intercalated and exfoliated nanostructure.
