Abstract: A prepolymer for use in preparing photocurable compositions is prepared by reacting an aliphatic diisocyanate having terminal isocyano groups and at least one alkyl side chain with a hydroxy-, mercapto- or amino-containing olefinically unsaturated compound. This prepolymer is compounded with a photosensitizer and, optionally, a polymercaptan to prepare photocurable compositions.

Abstract: Compounds of the formula ##STR1## wherein R.sup.1 is alkyl, alkenyl, cycloalkyl or aryl; R.sup.2 is alkyl, haloalkyl, alkenyl or aryl; and R.sup.3, R.sup.4 and R.sup.5 individually are alkyl or aryl, possess pesticidal activity.

Abstract: Prostan-1-ol esters and intermediates for their preparation are described; the former compounds exhibit improved organ specificity and a longer duration of activity at lower dosages than the corresponding non-esterified prostaglandins and are useful, inter alia, in triggering abortion, inducing labor and regulating the menstrual cycle.

Abstract: A process for the cross-linking or chain-extension of hydrocarbon polymers which contain ethylenically unsaturated groups which comprises forming an intimate mixture of the polymer with a mono-sulphonyloxycarbamate of the formula:A -- O -- CO -- NH -- O -- SO.sub.2 R (1)wherein A is an alkyl group, a cycloalkyl group, an alkenyl group, a substituted alkyl group, a substituted aryl group or a heterocyclic group, and R is an optionally substituted alkyl or aryl group.The process is useful for natural and synthetic rubbers. The rate and extent of cross linking may be modified by the additives such as tertiary amines or conventional rubber additives e.g. tetramethyl and zinc diethyl dithiocarbamates, which contain tertiary amino groups.

Abstract: New derivatives of amino acids which have the general formula ##STR1## are useful as angiotensin converting enzyme inhibitors.

Abstract: Herbicidal compositions consisting of an active herbicidal compound and an antidote therefor and the methods of use of the herbicide compositions are described herein. The antidote compound corresponds to the formula ##STR1## wherein R.sub.1 can be selected from the group consisting of alkyl, haloalkyl, halogen, isocyanate, alkenylamino, halophenylamino, phenyl, substituted phenyl wherein said substituents can be selected from alkyl, alkoxy, halogen, nitro, amino and haloalkylaminosulfonyl; R.sub.2 and R.sub.3 can be the same or different and can be selected from hydrogen, alkyl, haloalkyl, alkoxy, alkenyl, alkynyl, alkynoxy, haloalkoxycarbonyl, alkynoxycarbonyl, carbamoyl, haloalkylthio, diacetonitrilocarbamyl, phenyl, substituted phenyl wherein said substituents can be selected from alkoxy, halogen, hydroxy, nitro and carbamoyl, and R.sub.2 an R.sub.3 taken together form the ring structure alkyloxazolidyl.

Abstract: Ketoalkanesulfenylcarbamoyl and ketoalkanethiosulfenylcarbamoyl halides are useful intermediates in the preparation of pesticidally active carbamates.

Abstract: O-Alkyl-O-[1-alkyl-5-substituted-mercapto-triazol(3)yl]-phosphoric(phosphon ic) acid esters and esteramides of the formula ##STR1## in which R is alkyl with 1 to 6 carbon atoms,R' is alkyl, alkoxy, monoalkylamino or dialkylamino, each with up to 6 carbon atoms, or phenyl,R" is cyanoalkyl with 1 to 4 carbon atoms or alkenyl with 2 to 6 carbon atoms or, in the case where R' is alkylamino, may also be alkyl with 1 to 4 carbon atoms, andR'" is alkyl with 1 to 4 carbon atoms, which possess insecticidal and acaricidal properties.

Abstract: Poly-sulphonyloxyurethanes of the formulaA[O--CO--NH--O--SO.sub.2 --R].sub.n (1)wherein A is a linking group to which the oxygen atoms are attached at alkyl, cycloalkyl or aryl carbon atoms, n is an integer of value at least 2, and each R which may be the same or different, is an optionally substituted alkyl or aryl group, and their salts, especially salts with cations based on tertiary amines, are useful cross-linking or chain-extending agents for natural or synthetic polymers, or may be used as adhesives for binding these materials to each other or to metal substrates.
