Abstract: Improved injection moldability of polyethylene terephthalates is achieved by the addition of an epoxidized plasticizer and a nucleating agent cooperative with the epoxidized plasticizer to achieve the improved moldability even when the composition is injection molded using mold temperatures of at least as low as 93.degree. C.

Abstract: The present invention relates to a process for the viscosification of an organic liquid which comprises the steps of forming a first solution of an anionic polymer dissolved in the organic liquid; forming a second solution of a cationic polymer dissolved in the organic liquid; and mixing the first and the second solutions together to form an interpolymer complex of the anionic and cationic polymer in the organic liquid, wherein the organic liquid containing the interpolymer complex has improved viscosification properties. This solution possesses higher viscosity than the mean of the separate viscosities of the starting solutions at relatively low solids content. Moreover, these interpolymer complexes, in hydrocarbon solutions, can be formulated to exhibit shear thickening at increased shear rates. This property is useful in such technological applications as antimisting of the solvent.

Abstract: This invention relates to new emulsifiers for aqueous isocyanate emulsions and to their use as binders in the production of molded articles, in particular plates, e.g., from materials containing lignocellulose.

Abstract: A method for stabilizing organopolysiloxanes containing phosphonitrile chlorides or their reaction products which promote the condensation and/or equilibration of organopolysiloxanes which comprises reacting at least one compound containing at least one epoxy group per molecule with the phosphorus compounds present in the organopolysiloxanes.

Abstract: The present invention is directed to stabilizer compositions or thermoplastic polycarbonates based on phosphites and siloxane-oxetane compounds. These stabilizers protect the polycarbonate against heat and oxidative degradation, and in addition, increase the hydrolysis resistance of the polycarbonate. The present invention is also directed to a process for stabilizing polycarbonate and to the stabilized polycarbonate produced therefrom.

Abstract: Ester-carbonate interchange in blends of aromatic polycarbonates and poly(alkylene dicarboxylates) is inhibited by adding thereto an ortho-disubstituted hydroxyaromatic compound of the formula ##STR1## wherein X is hydrogen, lower alkyl or lower aryl.

Abstract: Disclosed is a method for sizing paper wherein the sizing agent employed is a hydrophobic cellulose reactive sizing agent such as a ketene dimer sizing agent. There is employed in combination with the sizing agent a novel sizing accelerator. Disclosed also is a novel sizing composition comprised of the sizing agent and the accelerator, the accelerator being a water-soluble nitrogen-containing reaction product of (1) a water-soluble polyaminopolyamide, such as that derived by reaction of adipic acid and diethylene-triamine; (2) an epihalohydrin, such as epichlorohydrin; and (3) a composition comprising, by weight, from about 20% to about 65% bis(hexamethylene)triamine, said composition being the residue obtained after recovery of hexamethylenediamine from its manufacture by hydrogenation of adiponitrile.

Abstract: An electronic device such as an integrated circuit is encapsulated within a silicone resin formulation having a protonated heterocyclic compound contained therein. The compound complexes with free anionic contaminants to form a non-migratory, non-corrosive protonated heterocyclic compound-anion complex, thereby preventing anionic attack of metallic circuit elements.

Abstract: An improved hydrolytically stable aromatic polyester-carbonate composition comprising in admixture an aromatic polyester-carbonate resin and a hydrolytically stabilizing amount of at least one stabilizing compound selected from epoxy silanes and epoxy siloxanes.
