Procedure for the preparation of methacrylated benzophenones |
| abstract |
Process for the preparation of benzophenone (meth) acrylates, characterized in that hydroxybenzophenone and (meth) acrylic acid anhydride are reacted in the presence of catalytic quantities of salts chosen from the group consisting of sodium, lithium or potassium acetates or (met ) Li, Na or K acrylates, wherein the substance amount ratio of (meth) acrylic acid anhydride to hydroxybenzophenone is 1.0: 1.0 to 1.6: 1.0. |
