AQUEOUS POLYMER DISPERSION WHICH CAN BE OBTAINED BY A RADICALLY INITIATED EMULSION POLYMERIZATION IN THE PRESENCE OF A MOLECULAR WEIGHT REGULATOR COMPOSITION |
摘要 |
The invention relates to an aqueous polymer dispersion containing a polymer, which can be produced by a radically initiated emulsion polymerization from ethylenically unsaturated, radically polymerizable monomers, wherein the polymerization of the monomers is carried out in the presence of a specific molecular weight regulator composition. The molecular weight regulator composition contains at least one mercaptoalkylcarboxylic acid ester of a C2 to C4 carboxylic acid and at least one oligomeric compound of formula R1-X-(A-S-)n-A-Y-R2, where R1 and R2 denote H or CH3-(CH2)0-2-C(=0)-, X and Y denote an oxygen atom or a sulfur atom, A denotes a divalent C1- to C18-alkylene group, and n denotes a number from 1 to 8. The invention further relates to a method for producing the aqueous polymer dispersion. The polymer dispersion can be used as a binder, adhesive, sizing agent for fibers, for producing coatings or for producing paper coating compounds. |
