Document Type and Number:
Japanese Patent JP2002541271
Kind Code:
A
Abstract:
These crosslinked microparticles between 10-300 nm in size are obtained by dispersion polymerization, in non-aqueous medium which is non-solvent for the polymer formed, of a composition of ethylenically unsaturated polymerizable compounds, comprising:at least one monomer A, comprising only one ethylenic unsaturation, giving the microparticles formed in the said non-aqueous medium self-stabilization during and after polymerization, without any addition of polymer having the function of a stabilizing agent, tither before, during or after polymerization,at least one compound B comprising at least two ethylenic unsaturationsand optionally, depending on the case:at least one compound C comprising only one ethylenic unsaturationand/orat least one compound D which is different from A, B and C and comprising at least one ethylenic unsaturation which can undergo radical-mediated polymerization and at least one second reactive function f1 which is other than an ethylenic unsaturation.
