Abstract: A mixture consisting essentially of:a) one or more dicarboxylic acid esters of the formula IROOC--A--COOR (I)in which the radicals R independently of one another are alkyl groups having 1 to 20 carbon atoms and A is alkylene having 1 to 20 carbon atoms, alkenylene or alkynylene each having 2 to 20 carbon atoms, cycloalkylidene or cycloalkenylidene each having 5 or 6 carbon atoms or phenyleneandb) the product (II) of the reaction of a triglyceride based on carboxylic acids having 2 to 30 carbon atoms and ethylene oxide and/or propylene oxide in the presence of a base,which is useful for the production of crop protection compositions, for herbicidal crop protection compositions, and for controlling undesired plant growth, and spray mixtures comprising the compositions.

Abstract: Agglomerated, finely divided, crosslinked vinylimidazole copolymers obtainable by free-radically initiated polymerization of N-vinylimidazoles of the formula ##STR1## where R, R.sup.1 and R.sup.2 are identical or different and each is H, C.sub.1 -C.sub.

Abstract: A process for the preparation of a stable water-in-oil emulsion of a hydrolyzed polymer of an N-vinyl amide of the formula ##STR1## in which R and R.sup.1 denote H or C.sub.1 -C.sub.6 alkyl, by the polymerization of a compound of the formula I alone or in admixture with another ethylenically unsaturated monomer in the presence of a polymerization initiator and emulsifier in the form of a water-in-oil emulsion, to form a water-in-oil polymeric emulsion, followed by hydrolysis of the polymer in the form of the water-in-oil polymeric emulsion in the presence of an acid or base and from 1 to 30 wt %, based on the polymer, of an emulsifier, the emulsifier used being a mixture of(a) from 5 to 95 wt % of a block or graft copolymer of the structure (A-B)m, (A)-B or (B)-A, in which in each case(a) from 5 to 95 wt % of a block or graft copolymer of the structure (A-B).sub.m, (A).sub.n B or (B).sub.

Abstract: This invention relates to polyphenylene oxides with high molecular weight (PPO) and to a process for their preparation by the reaction of polybasic aromatic carboxylic acids or their derivatives with polyphenylene oxides, and their use for the modification of plastics.
