PLASMA INDUCED COATING SOLIDIFICATION Russian patent published in 2009 - IPC C08J7/04 C08F2/52 

FIELD: chemistry.

SUBSTANCE: present invention pertains to a solidification method of compositions capable of polymerisation, and mainly to surface coatings, using plasma. The composition contains (a) at least one free radical monomer or oligomer compound, capable of polymerisation or (b) at least one compound, which under the effect of an acid, can be polymerised by cation alkyl- or aryl-containing cations or protons, and capable of polymerisation, polycondensation or polyaddition, or (c) at least one monomer, oligomer or polymer compound, which under the effect of a base, is capable of polymerisation, polycondensation or polyaddition, or a mixture of components (a) and (b), or a mixture of components (a) and (c); and (d) at least one photoinitiator, which is can be activated by a plasma discharge. The photointiator is chosen from a group consisting of a free radical photoinitiator, photolatent acid and a photolatent base. The composition is deposited onto a three-dimensional substrate, the shape of which is characterised by undercut or darkened parts. Solidification takes place in a plasma discharge chamber. Description is also given of the solidification method of a composition, containing, besides the above mentioned components, at least one light-stabilising compound or UV-radiation absorbing compound, a method of moulding objects from the composite materials, the substrate with deposition of coating on its surface and coatings, obtained using these methods.

EFFECT: obtaining a coating on complex substrates with good properties.
