Definitions

  • step (1) treating inert granules with the aqueous composition of step (1), and
  • the coated inert granules according to the invention comprises granules, which have a particle size of 0.1 to 10 mm, preferably 0.5 to 8 mm.
  • the granule may be of spherical, cylindrical, tablet-like or any other shape.
  • the coating of the inert granules comprises at least one polymer, preferably one polymer.
  • Said polymer comprises in polymerized form A) a vinyl lactam, and
  • Cs to C30 alkyl acrylates or Cs to C30 alkyl methacrylates are further suitable comonomers.
  • the acrylic and methacrylic esters with fatty alcohols with a chain length of from 8 to 18 carbon atoms where the alkyl radicals may be branched or unbranched, most preferably with a chain length of from 8 to 12 carbon atoms, where the alkyl radicals may be branched or unbranched.
  • R 1 is hydrogen or methyl
  • Suitable comonomers are vinyl ester of Ci to C30 organic acids.
  • Preferred are vinyl ester of aliphatic Ci to C30 carboxylic acids, more preferred of aliphatic C2-C12 car- boxylic acids and most preferred of acetic acid.
  • copolymers have weight average molecular weights, measured by GPC with methods known to those skilled in the art, from 10.000 g/mol to 100.000 g/mol, prefer- rably from 10.000 g/mol to 75.000 g/mol, particularly preferably from 10.000 g/mol to 50.000 g/mol.
  • Such polymer may be synthesized by radical polymerization according to known methods, for example as described in WO 2006/1 11327.
  • the polymer which coats the inert granules according to the present invention comprises in polymerized form alkyl (meth)acrylate and (meth)acrylic acid.
  • (meth)acrylic acid wherein the monomers add up 100 wt%.
  • These copolymers can have a weight average molar weight of 500 to 200000 Dalton, preferably 1000 to 100000 Dalton, in particular 2000 to 70000 Dalton. The molar weight can be determined by known procedures such as gel permeation chromatography.
  • Theses copolymers can have K values in accordance with Fikentscher measured at 1 % strength in 0.1 mol NaCI solution, from 5 to 80, preferably from 5 to 50, particularly preferably from 10 to 35.

  • step (2) the inert granules are coated with the aqueous composition of step (1 ) with known coating techniques.
  • an aqueous composition comprising the polymer and the active ingredient may be sprayed upon the inert granules. Spraying can take place in fluidized-bed coaters or in drums or rotating disks in which the inert gran- ules are rolled.
  • the inert granules are treated with the aqueous composition of step (1 ), preferably by mixing. The mixing may be preferably achieved by adding the aqueous composition of step (1) to the blank inert granules.
  • step (2) proceeds at ambient temperature, more preferebly at 15 to 25 0 C.
  • step (2) proceeds with a heat input of less than 6000 kJ/kg of coating polymer, more preferably of less than 3000 kJ/kg and most preferably without heat input.
  • Example 4 Release speed of fipronil with varying dispersant contents To determine the influence of the dispersant the release speed was measured at varying dispersant contents. For these measurements granules were produced as explained in example 2A, using polymer c) as polymer and varying dispersant 1 (lignine sulfonate) contents. The results can be seen in table 2. The weight percentage of lignin sulfonate is based on the final coated granule as calculated in example 2A.
