Abstract: A PROCESS FOR STORING A MONOMER PHASE WHICH IS LIQUID UNDER THE CONDITIONS OF STORAGE AND COMPRISES METHACRYLIC MONOMERS TO AN EXTENT OF ? 95 % BY WEIGHT AND HAS BEEN OBTAINED BY CONDENSATION OUT OF A GASEOUS PHASE OR BY MELTING A CRYSTALLINE PHASE, IN A STORAGE VESSEL, IN WHICH POLYMER OF THE MONOMER PRESENT IN DISSOLVED FORM IN THE LIQUID MONOMER PHASE IS REMOVED THEREFROM ON THE ROUTE FROM ITS GENERATION INTO THE STORAGE VESSEL, AND ALSO A PROCESS FOR WITHDRAWING LIQUID MONOMER PHASE FROM THE STORAGE VESSEL IN WHICH POLYMER OF THE MONOMER PRESENT IN DISSOLVED FORM IN THE MONOMER PHASE IS LIKEWISE REMOVED.
