Document Type and Number:
Japanese Patent JP2642432
Kind Code:
B2
Abstract:
In a first stage of this process an elastomer latex is prepared in aqueous emulsion in the presence of an ionic surface-active agent, from at least one ethylenically unsaturated monomer; then, in a second stage, at least one vinyl monomer which is insoluble in water or poorly soluble in water is added to the latex thus obtained. According to the invention, the ionic charges carried by the said latex are quantitatively neutralised by adding to the latex + monomer(s) system a transfer agent carrying ionic charges of opposite sign to those of the surfactant employed in the first stage, in order to produce the transfer of the particles of the said latex into the said vinyl monomer(s); and, in a third stage, a suspension or bulk polymerisation is performed on the phase consisting of the said monomer(s) from the second stage and containing the transferred latex particles.
