The invention relates to novel microcapsule formulations of The invention further relates to a process for the preparation of these microcapsule formulations and to their use for applying agrochemical active compounds.

Microcapsule formulations

Use of gel formulations as dressing agents for plant seed

The invention relates to a process in which a melt is mixed with, and emulsified in a colder aqueous phase at a temperature below the crystallization point of the molten compound, the melt only solidifying in the form of the dispersed particles after the emulsification step. To this end, the melt is sprayed into the aqueous phase to form a preliminary emulsion (12) and the preliminary emulsion is finely dispersed for 0.005 s to 0.15 s in a following homogenization nozzle (8) to form an emulsion (15) which then solidifies to form the final crystal suspension. The particle size can be clearly and reproducibly adjusted through the nozzle pressure during the emulsification step. The process may be used in particular for the production of highly concentrated dispersions of high-melting organic materials.

Production of dispersions of spherical particles by crystallization of

Polyoctenamers, in which more than 80% of the C=C-double bonds are in the cis-configuration, with a second order transition temperature of approximately -90.degree.C, a crystallisation temperature of from -30.degree. to +10.degree.C and a melting point of +10 to +40.degree.C and a process for its production, wherein cyclooctene and, optionally, up to 20% by weight, based on the monomer total, of another cyclic olefin are polymerised in an inert organic solvent at temperatures of from -50.degree. to +10.degree.C in the presence of a catalyst of

Polymerisation of cyclooctene

A process for the polymerisation of cyclooctadiene-(1,5) wherein cyclooctadiene-(1,5) is polymerised on halides of tungsten, molybdenum, tantalum, or rhenium as catalyst in the presence of bicyclo-[2,2,1]-heptadienes-(1,5) of the general formula (I) ##SPC1## as activator, R.sub.1, R.sub.2, R.sub.3 and R.sub.4 denoting independently of each other, a monovalent hydrocarbon radical or hydrogen.
