Abstract

Abstract Translated from German Die Erfindung betrifft hydrophile Latexpartikel, die aus einem Homo- oder Copolymerisat von in Wasser schwerlöslichen Monomeren besteht, sowie Verfahren zur Herstellung dieser hydrophilen Latexpartikel. Hierzu werden ein in Wasser schwerlösliches Monomer oder verschiedene in Wasser schwerlösliche Monomere in Wasser dispergiert und unter Ausschluß von Sauerstoff durch Emulsionspolymerisation in Anwesenheit eines wasserlöslichen, Radikale bildenden Initiators, jedoch ohne jeden Zusatz eines Emulgators, Stabilisators oder Netzmittels homo- oder copolymerisiert. Ferner betrifft die Erfindung ein diagnostisches Mittel, das die hydrophilen Latexpartikel als Träger für direkt oder über ein Kupplungsmittel kovalent gebundene biologisch und/oder immunologisch aktive Substanzen enthält. The invention relates to hydrophilic latex particles consisting of a homopolymer or copolymer of monomers which are sparingly soluble in water, and to processes for producing these hydrophilic latex particles. For this purpose, a poorly water-soluble monomer or various water-slightly soluble monomers are dispersed in water and homo- or copolymerized with the exclusion of oxygen by emulsion polymerization in the presence of a water-soluble, radical-forming initiator, but without any addition of an emulsifier, stabilizer or wetting agent. The invention further relates to a diagnostic agent which contains the hydrophilic latex particles as a carrier for biologically and / or immunologically active substances which are covalently bound directly or via a coupling agent.
