Herbicidal sulphonylaminocarbonyltriazolinones having two substituents bonded via oxygen, of the formula ##STR1## in which R.sup.1 represents hydrogen or an optionally substituted radical from the series comprising alkyl, alkenyl, alkinyl, cycloalkyl, cycloalkenyl and aralkyl,

Herbicidal sulphonylaminocarbonyltriazolinones having two substituents

Intermediates for herbicides, the intermediates having the formula ##STR1## in which R is i-propyl, n-butyl, i-buty, s-butyl or cyclopropyl.

Herbicidal substituted triazolinones

This invention relates to novel polycarbonates having hydroxyl end groups and an average molecular weight of 500 to 12,000, as determined by measuring the OH number, and being based on dimer diols containing either 36 or 44 carbon atoms. These novel polycarbonates are particularly suitable for the use in a process for the production of polyurethane plastics which are stable to hydrolysis and oxidation.

Polycarbonate diols, their preparation and use as starting products for

Alkoxytriazolinones of the general formula (I), ##STR1## in which R.sup.1 and R.sup.2 independently of one another represent in each case optionally substituted alkyl, alkenyl, alkinyl, cycloalkyl, cycloalkylalkyl, aryl or arylalkyl,

Process for the preparation of alkoxytriazolinones

Alkoxytriazolinones of the formula (I), ##STR1## in which R.sup.1 and R.sup.2 independently of one another represent in each case optionally substituted alkyl, alkenyl, alkinyl, cycloalkyl, cycloalkylalkyl, aryl or arylalkyl,

##STR1## in which R.sup.1 represents hydrogen, amino, or an optionally substituted alkyl, alkenyl, alkinyl, cycloalkyl, aralkyl, aryl, alkylamino, cycloalkylamino or dialkylamino radical,

Herbicidal sulphonylaminocarbonyltriazolinones having substituents

Water soluble or water dispersible polyurethane, which are suitable as thickeners for aqueous systems and prepared from a selected alcohol component a) based on a hydrophilic/hydrophobic mixture of alcohols and an isocyanate component b), and to their use for thickening aqueous systems.

Polyurethane thickeners and their use for thickening aqueous systems

Alkoxytriazolinones of the general formula (I), ##STR1## in which R.sup.1 and R.sup.2 independently of one another represent in each case optionally substituted alkyl, alkenyl, alkinyl, cycloalkyl, cycloalkylalkyl, aryl or arylalkyl, (which can be used as intermediates for the preparation of herbicidal active compounds) are obtained in very good yields and in high purity by reacting iminocarbonic diesters (II) with carbazinic esters (III) ##STR2## in which R.sup.3 and R.sup.4 in each case represent, for example, alkyl or aryl, at -20.degree. C. to +120.degree. C. (1st step) and subjecting the semicarbazide derivatives (IV) formed in this process with elimination of R.sup.3 -OH ##STR3## to a cyclizing condensation reaction in the presence of a base at +20.degree. C. to 100.degree. C. with elimination of R.sup.4 -OH, if appropriate after intermediate isolation (2nd step).

Sulphonylaminocarbonyltriazolinones

7 Herbicidal 5-alkoxy-1,2,4-triazol-3-(thi)ones of the gerneral formula ##STR1## (in which the radicals R.sup.1, R.sup.2, R.sup.3, X and Y have the meanings given in the description), processes for their preparation, and their use as herbicides, and also new intermediates of the formula (II) ##STR2##
