  • THICKENED POLYMER
    Publication number: 20180319911
    Abstract: The invention relates to a thickened preparation comprising a polymer which can be obtained by radical emulsion polymerization of at least one acidic vinyl monomer or salt thereof, at least one non-ionic vinyl monomer, in particular preferably a hydrophobic non-ionic vinyl monomer, at least one monomer containing an unsaturated terminal group and a polyoxyalkyene portion, at least one crosslinking monomer, optionally a protective colloid, and is characterized in that the polymerization is controlled such that the gelling effect occurs at least at times, which is achieved by the monomer addition (dosing time) taking place for 40 minutes, particularly preferably for 30 minutes.

  • Method For The Manufacture Of Nanoparticle Complexes And Triblock Polymer Ligands And Products Thereof
    Publication number: 20120045398
    Abstract: The present invention relates to the manufacture of triblock polymer ligands (30) and nanoparticle complexes (80). The nanoparticle complexes (80) comprise a capped nanoparticle (10) and the triblock polymer ligand (30). The triblock polymer ligand (30) consists of a binding polymer (40), a hydrophobic polymer (50) and a hydrophilic functionalisable polymer (60). The binding polymer (40) attaches to the capped nanoparticle (10).
