Abstract: Provided are novel polyester compositions containing copper phthalocyanine sulfonamide colorants copolymerized therein. Also provided are amorphous color concentrates, partially-crystalline color concentrates and semi-crystalline color concentrates. These polyester compositions are particularly useful for use as colored packaging materials and for colorants for personal, medical, and home care products where non-extractability of the colorant residue is important.

Abstract: Preceramic polymer dispersions which have particular utility in providing protective ceramic coatings on carbon/carbon composites, graphite, carbon fibers, and other normally oxidizable materials are prepared by dispersing about 0.25-2.0 parts by weight of silicon metal, about 0.25-2.0 parts by weight of silicon tetraboride, about 0.25-2.0 parts by weight of silicon hexaboride, and about 0-2 parts by weight of silicon carbide in the product obtained by dispersing about 0.1-1.0 part by weight of a Group IVA metal salt or an organometallic Group IVA metal compound in an organic solvent solution containing one part by weight of a polysilazane and, if desired, heating the Group IVA compound/polysilazane dispersion to convert it to a solution.

Abstract: Polyesters, especially poly(ethylene terephthalate) and poly(butylene terephthalate), having a substantial proportion of free carboxylic acid groups are caused to react with polyepoxy compounds, especially poly(O- or N-epoxyalkyl-substituted) cyclic amides, imides and amidates and preferably triglycidyl isocyanurate, in the presence of various amines or salts as catalysts. The preferred catalysts are fatty acid salts such as sodium sterate. The products have very high melt viscosities and are useful in such operations as blow molding.

Abstract: Polymers with conjugated backbones, both polyacetylene and polyaromatic heterocyclic types, are doped with electron-donor agents to increase their electrical conductivity. The electron-donor agents are either electride dopants made in the presence of lithium or dopants derived from alkalides made in the presence of lithium. The dopants also contain a metal such as cesium and a trapping agent such as a crown ether.

Abstract: The adhesion of organopolysiloxane compositions curable by a platinum catalyzed hydrosilation reaction to various substrates, particularly plastics, is improved by the presence in said compositions of (1) an organosilicon compound containing an ethylenically unsaturated group and at least one alkoxy group and (2) at least one member from a specified class of compounds of aluminum or zirconium.

Abstract: Reduction in the adhesion to glass of thermoplastic, plasticized polyvinylbutyral molding compositions, in particular sheeting, by the addition of a metal salt and/or metal chelate of an enolizable .beta.-diketone, or mixtures of these compounds, as an non-stick agent, preferably in amounts of 0.003 to 0.3% by weight, relative to the plasticized polyvinylbutyral. It is preferable to employ the non-stick agent in the form of a solution in the plasticizer. The use of the sheeting having an adhesion to glass reduced in accordance with the invention as a laminating layer for the production of glass laminates.

Abstract: Conjugated backbone polymers (e.g., polyacetylene), especially formed into a battery electrode, are contacted with a compound MR where M is an alkali metal and R is alkyl of 1-12 carbons, phenyl or alkylphenyl of 7-12 carbons.
