Description

Verfahren zur Herstellung von Polymerisationsprodukten Es wurde gefunden, daß man technisch wertvolle 1-lischpolymerisate herstellen kann, wenn man 13utadien tnit mindestens der gleichen Menge Styrol in Gegenwart von höchstens 5% der Gesamtmenge der vorhandenen polymerisierbaren Verbindungen an Acrylnitril, Acrylestern oder deren Derivaten polymerisiert. Unter Derivaten werden im vorliegenden Falle insbesondere die von der Methacrylsäure sich ableitenden Verbindungen verstanden. In der Regel kommt man mit erheblich unter 50/0 liegenden Mengen an Acrylsäureverbindungen aus, z. B. 2 bis 3%. Die Polymerisation wird zweckmäßig in Emulsion durchgeführt. Beispiel In ioo Teilen einer 2%igen wäßrigen Lösung eines höhermolekularen Fettalkoholsulfonates werden 2o Teile Styrol, 7 Teile Butadien und 2 Teile Acrylnitril sowie i Teil polyacrylsaures Natrium dispergiert. Unter Zusatz von o,i % Ammoniumpersulfat wird bei einer innerhalb 6 Stunden von 6o auf 95° steigenden Temperatur polymerisiert, wobei eine Emulsion erhalten wird, die beispielsweise ohne weiteres für Anstrichzwecke verwendet werden kann, da sie pigmentverträglich ist.Process for the production of polymerization products It has been found that one can produce industrially valuable 1-copolymerizates if one uses 13utadiene with at least the same amount of styrene in the presence of a maximum of 5% of the total amount the existing polymerizable compounds of acrylonitrile, acrylic esters or their derivatives polymerized. In the present case, derivatives are in particular understood the compounds derived from methacrylic acid. Usually it is possible to manage with amounts of acrylic acid compounds that are considerably below 50/0, z. B. 2 to 3%. The polymerization is expediently carried out in emulsion. example In 100 parts of a 2% strength aqueous solution of a higher molecular weight fatty alcohol sulfonate 20 parts of styrene, 7 parts of butadiene and 2 parts of acrylonitrile and 1 part of polyacrylic acid are used Sodium dispersed. With the addition of o, i% ammonium persulphate, an inside Polymerized for 6 hours from 6o to 95 ° increasing temperature, with an emulsion which are readily used, for example, for painting purposes because it is compatible with pigments.
