The compounds possess insecticidal and herbicidal activity.
Abstract: Triazines of the formula ##STR1## wherein R is chlorine, methoxy or methylthio, R' is alkyl, alkenyl or alkoxyalkyl; R.sup.2, R.sup.3, R.sup.4 and R.sup.5 are hydrogen or alkyl; R.sup.6 is alkyl, aryl or haloaryl; and Y is oxygen or sulfur, are useful as herbicides.
Abstract: A paper web having an adhesive composition coated thereon wherein the adhesive consists essentially of latices, at least one being alkali-swellable or alkali-soluble and at least one not being alkali-swellable or alkali-soluble, the pH of the composition being such that the alkali-swellable or alkali-soluble latex remains in the unswelled or undissolved condition.
Abstract: An improved process for the preparation of methacrylamides from primary amines, methacrylic esters, and base catalysts such as alkoxides and amides. Some products are obtained in the form useful as comonomers in the preparation of elastomers.
Abstract: Butyl rubber possessing a low unsaturation content is compounded with a bromomethyl alkylated phenolic resin and a metal compound such as stannous chloride and the composition used to prepare bladders for the vulcanization of pneumatic vehicle tires.
Abstract: A planographic printing plate which is imaged by means of a laser beam in combination with overall exposure to ultraviolet light and developed by means which are conventional in lithographic art.
Abstract: Amide compounds such as N-(phenyl)propenamide and N-(phenyl)-2-methylpropenamide are added to certain diene polymers such as SBR, NBR and natural rubber, preferably prior to compounding with reinforcing agents such as carbon black, thereby improving the hardening resistance of the subsequently sulfur vulcanized polymer.
Abstract: A paintable rubber composition of SBR rubber and EPDM rubber, containing, as a stiffening agent, a high styrene resin of butadiene and styrene. This rubber composition can be used in molded and extruded products such as sight shields, automotive facia, fender liners and automotive door panels.
Abstract: A phenolic antioxidant is combined with a sulfur-containing compound to form a larger antioxidant molecule. The resulting compounds are non-staining and prevent polymer degradation.
Abstract: Gels are formed from silica powders and hydrochloric acid. The gels can then be impregnated into a polymeric foam and the resultant sheet material can then be used in applications where the transport of chloride ions is desired. Specifically disclosed is the utilization of the sheet in electrically rechargable redox flow cells which find application in bulk power storage systems.

Abstract: Compounds of the formula ##STR1## wherein R is an alkyl group or an alkenyl group, each substituted with 1 to 5 halogen atoms of atomic number 9 to 35, and X is halogen of atomic number 9 to 35, nitro, cyano, lower alkyl, lower alkoxy or trifluoromethyl and n is 0 or an integer of 1 to 3, possess fungicidal activity.
Abstract: A process for separating mixtures of close boiling, high-molecular weight alkenes and alkanes which employs phenoxide-catalyzed alkyl displacement.
Abstract: An N-(aminothio)-phthalimide such as N-(morpholinothio)-phthalimide is reacted with a compound having the structure RSH or a metallic salt thereof, for example, benzene thiol, to produce a compound having the structure RSSNR.sup.1 R.sup.2, such as N-(phenyldithio)-morpholine. Compounds prepared according to this process are either accelerators or retarders.
Abstract: An improved vanadium-phosphorus mixed oxide is prepared by a unique method employing an organic medium. The substantial intrinsic surface area and the microcrystalline structure of the new oxide result in advantageous activity and selectivity effects in the catalysed vapor phase oxidation of n-butane to maleic anhydride. These oxides are also useful for the production of acid anhydrides from suitable hydrocarbon feeds.
Abstract: A process for polymerizing 2-pyrrolidone utilizing an agitated reaction mixture containing an inert nonsolvent and an insoluble salt in order to produce a particulate, or easily comminuted, solid product.
Abstract: Carboxylic acids are prepared from high-molecular-weight paraffins by vapor phase cracking at a temperature of at least about 500.degree.C and a residence time of from about 0.1 seconds to about 10 seconds in the presence of carbon dioxide.
Abstract: Compounds of the formula ##STR1## wherein R, R.sup.1 and R.sup.2 are hydrogen, halogen, hydroxy, alkyl or alkenyl optionally substituted with halogen atoms and R.sup.3 is a haloalkyl, haloalkenyl or aryl group, possess morphogenetic hormonal mimetic insecticidal activity.
Abstract: A process for producing hydroxyacetic acid which comprises contacting carbon monoxide with formaldehyde and a catalyst comprising hydrogen fluoride in a reaction zone at a temperature between 0.degree. and 100.degree. C and a pressure between 10 and 4000 psig. Oxydiacetic acid is also produced by this reaction. The ratio of hydroxyacetic acid to oxydiacetic acid is increased by adding water to the reaction mixture.
