Patent ID: 8790760

Claim:
A container comprising, a plastic material, a liquid formulation comprising a crop protection substance selected from the group consisting of herbicides, fungicides, insecticides, acaricides, nematicides, growth regulators and bactericides, and a polymeric organofluorine coating, wherein said coating is present on the interior of said container and has a multiplicity of perfluoroalkyl groups on the surface of said coating, said interior comprises said inner walls, said formulation has reduced adhesion to said inner walls and said coating has a thickness from 0.01 to 500 μm, where the perfluoroalkyl groups are linear groups of the formula (CF 2 ) n F, where n is an integer in the range from 2 to 20 and wherein said coating comprises said perfluoroalkyl groups in an amount from 1% to 50% by weight of said coating, wherein said coating comprises at least one comb polymer, wherein side chains on said comb polymer comprise said perfluoroalkyl groups wherein said comb polymer is composed of ethylenically unsaturated monomers (M), said monomers (M) comprising: i) at least one first monoethylenically unsaturated monomer M1 which has at least one said perfluoroalkyl group, and ii) at least one second monoethylenically unsaturated monomer M2 which does not contain any said perfluoroalkyl group on said monomer M2.
