STABILIZER BASED ON POLYOL PEROXIDE AND PROCESS FOR MAKING POLYMER POLYOLS

The present invention refers to macroinitiators of general formula (HO)x-Ra-(O-C(═O)-Rb-C(═O)-O-O-Rc)y, a process for obtaining them, as well as their use in the synthesis of polymer polyols. It also relates to the resulting polymer polyol, as well as to a dispersant obtainable in the process for pr...

More Information
Summary:The present invention refers to macroinitiators of general formula (HO)x-Ra-(O-C(═O)-Rb-C(═O)-O-O-Rc)y, a process for obtaining them, as well as their use in the synthesis of polymer polyols. It also relates to the resulting polymer polyol, as well as to a dispersant obtainable in the process for preparing the polymer polyol, said dispersant being obtained by reacting said macroinitiator with at least one ethylenically unsaturated monomer.
