Abstract: A resin composition having nice color tone and high crack-resistance as well as flame-retardancy is obtained by blending(A) 100 weight parts of a resin composition containing a rubber-reinforced vinyl aromatic polymer and polyphenylene ether represented by the following general formula: ##STR1## wherein each of R.sub.1 and R.sub.2 represents a monovalent residue such as the same or different alkyl group having 1-4 carbon atoms, aryl group, halogen and hydrogen, and n represents the polymerization degree or a polyphenylene ether onto which a vinyl aromatic compound is graft-copolymerized, in which the polyphenylene ether content is 5-70 wt. % (based on the weight of the resin part),(B) 1-30 weight parts of a halogenated aromatic compound and(C) 0.5-20 weight parts of a non-crystalline ethylene-propylene copolymer.

Abstract: A method for stabilizing organic polymers against copper-catalyzed oxidative decomposition by means of N,N-bis-salicyloyl hydrazine as a metal deactivator is described wherein dust development of the metal deactivator is precluded with certainty and negative property changes of the stabilized organic polymers are avoided. For this purpose, it is provided that a paste which contains finely-crystalline N,N'-bis-salicyloyl hydrazine in fine distribution in a liquid to wax-like aliphatic hydrocarbon of low volatility is worked into the polymer. The method is particularly well suited for stabilizing polyolefins for cable and wire insulation.

Abstract: A novel flame-retardant ethylene polymer composition comprising a copolymer consisting essentially of ethylene and an olefinically unsaturated silane compound such as vinyltriethoxysilane, a silanol condensation catalyst such as dibutyltin dilaurate, and a flame retardant such as a chlorinated polyethylene.

Abstract: The invention relates to plastics moulding compounds which have been flame-proofed with organic chlorine- or bromine-containing compounds, said moulding compounds containing at least one aerosol selected from the group comprising the highly dispersed silicates, highly dispersed alumina, and highly dispersed titanium dioxide, and, optionally, a dibasic or tribasic oxyacid of phosphorus or an ester thereof. These moulding compounds have a reduced corrosive action on contact metals.

Abstract: Ink compositions especially suitable for printing electronic circuit patterns on a substrate such as a flexible polyester substrate; methods for developing electrolessly and electrolytically the circuit configurations as articles of manufacture; flexographic printing with the ink composition has been disclosed as the preferred method.

Abstract: Fiber-treating compositions are disclosed which contain two types of organofunctional polysiloxanes, one bearing amino-functional organic radicals or carboxy-functional organic radicals or epoxy-functional radicals and the other bearing another type of organofunctional radicals selected from the same group. In addition, at least one of the organofunctional polysiloxanes bears one or more polyoxyalkylene radicals.These compositions are useful for durably treating fibers to provide several benefits such as antistatic character, moisture/perspiration absorbability, stain resistance, pliability, smoothness, crease resistance and compression recovery.

Abstract: A curable urethane material which shows no change in volume on polymerization and curing is prepared from polyisocyanate compound, polyhydroxy compound and a new compound 1-alkyl-4-hydroxymethyl-2,6,7-trioxabicyclo[2,2,2]octane.

Abstract: The invention provides a process for preparing an aqueous emulsion or dispersion of a partly water-soluble material, and optionally further conversion of the prepared dispersion or emulsion to a polymer dispersion when the partly water-soluble material is a polymerizable monomer. In a first step a dispersion of polymer particles is prepared containing one or more materials having a very low solubility in water, then in a second step there is added the partly water-soluble material which diffuses into the particles from the first step, and then, if the partly water-soluble material is a polymerizable monomer, polymerization may be effected.
