Abstract: Compositions of an aromatic polycarbonate, a polysulfone carbonate and a filler are disclosed which have good electrical properties, high modulus and molten solder resistance.

Abstract: Preparation of hydrolyzable polyester resin comprising reacting polycarboxylic acid and polyhydric alcohol components, which is characterized by using, as at least part of said polyhydric alcohol component, a metallic salt of hydroxy carboxylic acid of the formula defined and effecting the polycondensation at a temperature which is no more than the decomposition temperature of said metallic salt. The polyester resins are useful as resinous vehicle of varnishes and antifouling paints.

Abstract: A composition comprising a thermoplastic resin in admixture with a mold release effective amount of an acrylate.

Abstract: A composition comprising a thermoplastic resin and a mold release effective amount of a vinyl ether.

Abstract: Polyester latex compositions comprising an aqueous continuous phase having dispersed therein loadable hydrophobic polyester particles are disclosed. In the latex(a) substantially all of the polyester particles are less than about 0.2 micron in diameter;(b) the polyester contains from about 0.5 to 5.0 mole percent dicarboxylic acid derived repeating units having a component selected from the group of salts consisting of alkali metal or ammonium iminodisulfonyl and alkali metal or ammonium sulfonate.The latex contains from 0 to 3% surfactant based on the total weight of the polyester.The polyester is optionally loaded with a hydrophobe. Coated layers of the composition are water resistant.

Abstract: A composition comprising a thermoplastic resin and a mold release effective amount of an olefin.

Abstract: A stable polyol-alkali metal silicate emulsion is produced by mixing an aqueous solution of an alkali metal silicate or alkali metal metasilicate pentahydrate, a liquid polyol and a small amount of a salt of an alkali metal compound and a weak acid while heating the mixture to between 40.degree. C. and 100.degree. C. and agitating until the mixture emulsifies.

Abstract: A melt processable poly(ester-carbonate) which is capable of forming an anisotropic melt phase is provided. The poly(ester-carbonate) of the present invention consists essentially of the recurring units (a) 6-oxy-2-naphthoyl moiety, (b) dioxyaryl moiety, (c) carbonyl moiety (i.e., carbonate moiety), and, optionally, (d) other aromatic moiety derived from aromatic hydroxyacid and (e) carbocyclic dicarboxyl moiety in the proportions indicated. Preferably, the dioxyaryl moiety is derived from hydroquinone, the carbonic acid moiety which is derived from a diarylcarbonate (e.g., diphenyl carbonate), and the additional aromatic moiety which is derived from an aromatic hydroxyacid is derived from hydroxybenzoic acid. The resulting poly(ester-carbonate) exhibits a melting temperature below approximately 400.degree. C., preferably below approximately 350.degree. C. The poly(ester-carbonate) of the present invention is preferably formed by a melt polymerization technique.

Abstract: Mixing (a) a carboxylic acid, (b) a divalent or trivalent metal oxide or hydroxide and (c) a foundry molding sand in the presence of an aqueous solution of (d) a carboxyl-group-containing polymer or (e) water followed by shaping and curing can provide sand molds having sufficiently high green strength without contamination of the working environment. The molding sand composition has excellent processability, which means filling of shapes or molds with the sand can be done with ease. The sand molds manufactured in this way can be disintegrated by a simple procedure. Therefore the molding sand can be used over and over again and does not cause environmental pollution due to disposal of the molding sand.
