ABSTRACT:
The present invention relates to the use of poly acrylic and/or methacrylic macroinitiators in the free radical addition reaction of vinyl aromatic monomers to improve the properties of the resulting copolymer and/or composite. More particularly, the present invention relates to the production of poly acrylic and/or poly methacrylic macroinitiators having nitroxyl end groups. Using such macroinitiators in the free radical addition reaction of vinyl aromatics such as polystyrene compatibilizes the acrylic monomer in the vinyl aromatic matrix thereby improving the properties of the resulting polymer.
