Abstract:
Hydroxypolyamides, hydroxypolyamide products, and post-hydroxypolyamides are disclosed as gel forming agents. Hydroxypolyamides and post-hydroxypolyamides are prepared from known methods. Hydroxypolyamide products are produced from a modified polymerization procedure which utilizes strong base for deprotonation of ammonium salts from the esterification of stoichiometrically equivalent polyacid:polyamine salts. The hydroxypolyamide products are capable of gel formation at lower concentrations than hydroxypolyamides and post-hydroxypolyamides from the known methods of preparation, and are therefore superior gel forming agents.
Abstract:
The mechanical properties of urea formaldehyde resins may be improved by incorporating therein polyvinyl alcohol. The polyvinyl alcohol may be incorporated during pre-mixing, mid mixing, and/or post mixing of the resin components. Resins prepared using polyvinyl alcohol are particularly desirable in articles requiring improved mechanical strength and water resistance, as compared to similar resins prepared without the polyvinyl alcohol such as shingles.
Abstract:
In an aspect, the present disclosure relates to a polyamide solution comprising an aromatic polyamide and a solvent, wherein a Young's modulus of at least one direction of a cast film produced by casting the polyamide solution on a glass plate is 3.0 GPa or more, and a tensile strength of the cast film is 100 MPa or more and 250 MPa or less. In another aspect, the present disclosure relates to a polyamide solution comprising an aromatic polyamide and a solvent, wherein a Young's modulus of at least one direction of a cast film produced by casting the polyamide solution on a glass plate is 3.0 GPa or more, and an aromatic polyamide of the polyamide solution has a constitutional unit represented by following general formulae (I) and (II).
Abstract:
A dispersion having from one to sixty percent by weight of total dispersion of a solids component dispersed in an organic continuous phase is useful as a coating for substrates. The solids component contains 40-95 weight-percent of a polyolefin containing only carbon and hydrogen and that has a number average molecular weight that is greater than 400 gram per mole, 5-40 weight-percent of an amine salt of a functionalized polyolefin; and 0-20 weight-percent of optional additives, wherein weight-percent is based on total weight of solids and wherein the dispersed particles have an average particle size of less than 35 micrometers and the organic phase is a dispersion support medium for the polyolefin and amine salt of a functionalized polyolefin.
Abstract:
Redispersible polymer powder compositions which include a polyglycol in admixture with a redispersible polymer powder (RDP), which powder includes a codried mixture of a carboxylated, water insoluble film-forming styrene butadiene polymer and a colloidal stabilizer, results in cement compositions having unexpectedly superior overall bonding strength and adhesion after water immersion. Use of the polyglycol provides good workability or ease of troweling during application. In addition, the RDP composition, which includes the RDP and the polyglycol, provides the cement-based composition with excellent abrasion resistance, surface appearance, and color. Also, the RDP composition provides for at least a 30% reduction, for example a 50% or more reduction in the amount of retarder or retardant employed in the dry mix formulation for cement compositions, such as self leveling flooring compounds or compositions, and cement-based tile adhesives.

Abstract:
A low damping high strength polymer with a blend of a terpolymer and a tetrapolymer utilizing ethylene, propylene, and non-conjugated dienes. This polymer allows for the creation of products with high diene contents and broad molecular weight distributions while utilizing a continuous flow reactor and a known catalyst. The polymer allows for these products to be made without gelling or fouling of the reactor, which are problems known in the art.

Abstract:
The present invention refers a procedure for preparation of a reflective and oxide inhibiting coating consists of adding hard water, a series of compounds such as titanium dioxide, calcium hydroxide at 95%, an acrylic polymer, hydroxy methyl cellulose, sodium hexametaphosphate at 10% y monoethylen glycol, maintaining specific conditions of pH and viscosity during process. The resulting coating of this process, presents highly adhesive actions, as well as a high level of reflection to solar rays, which place it as a oxide inhibitor, that no require previous sealed when it is applied to steel and/or galvanize surfaces.
