This disclosure relates to the use of certain disilazane treated colloidal silicas as processing aids for rubbery copolymers of styrene and butadiene.

A detergent composition of the low temperature bleaching type comprises an inorganic persalt, for example sodium perborate, an inorganic peracid precursor, for example N,N,N',N-tetraacetyl ethylene diamine, a cotton substantive fluorescent agent of the 4,4'-di(sym-triazinylamino)-stilbene-2,2'-disulphonate type and not more than 0.001 per cent of a triazine derivative of specified formula. The compositions have a decreased tendency to discolor and form molodours during storage.

Ferrophosphorus containing at least 1 percent silicon by weight is admixed with calcium carbonate and formed into an integral composite, the silicon content of which is converted to silica upon addition of the composite to molten iron, steel, or alloys thereof. The composite provides, for example, a useful effective low silicon source of phosphorus and alloying constituents for iron, steel and their alloys.

There is disclosed polyamide compositions of fractionated polymeric fat acids and diamines of the formula where R' is an alkyl group having from 1-4 carbon atoms and n is an integer designating the number of substituent groups present. When n is O, the ring is accordingly an unsubstituted cyclohexyl ring. Illustrative diamines are 4,4'-diaminodicyclohexylmethane and 4,4'-diamino-3,3'-dimethyldicyclohexylmethane. Copolymerizing dibasic acids such as suberic, sebacic or dodecanedioic acids may als...

The photosensitive compositions comprising (A) an unsaturated polyester, (B) acrylic acid and (C) a photopolymerization initiator, said unsaturated polyester being produced from an alcoholic component comprising at least one etherdiol having one to four ether-oxygen groups in the main chain and an acidic component comprising at least one unsaturated dicarboxylic acid, anhydride or dimethyl or diethyl ester thereof and having an average molecular weight of 1,500 to 50,000 and a double bond concen...

Room temperature vulcanizing silicone elastomers are prepared by the addition of a novel cross-linking agent such as acetoxypropenylenyltriacetoxysilane to a silanol chain-stopped polydiorganosiloxane fluid. These compositions are stable, free flowing fluids in the absence of moisture but cure to a rubbery, solid elastic state upon exposure to moisture. These compositions are particularly useful as adhesives in difficult bonding situations such as attaching glass window panes to aluminum window ...

The invention provides pharmaceutical and veterinary compositions including as active ingredient a known derivative of di-(2-thienyl)borinic acid or phenyl-2-thienylborinic acid, for use in the treatment of bacterial infections, particularly those caused by Gram-negative bacteria.

Novel rubbery photoresist compositions are described which include a hydroperoxide to improve adhesion of the resist to the substrate on which it is coated.

A water-dilutable coating composition particularly adaptable for electro-deposition comprising water, a water-miscible solvent, and an ammonia or amine soap of a condensation product of an adduct of an .alpha.,.beta.-ethylenically unsaturated dicarboxylic acid and an ester of a hydroxyl-free drying or semi-drying oil, unmodified or modified with rosin, is described. The condensation product will comprise from 10 to 25 percent by weight of a dienophilic compound, 75 to 90 percent by weight of the...

High impact strength polypropylene compositions are prepared by blending polypropylene, a halogenated polyolefin, and a rubbery ethylene-propylene copolymer. These compositions can be made fire-resistant by blending therein a halogenated bis(cycloalkenyl) compound, optionally further with antimony oxide, without loss of desired physical properties.
