Abstract

Novel substantially random functionalized interpolymers and processes for making them are disclosed. The novel interpolymers include those prepared from ethylene and vinyl aromatic monomers such as ethylene-styrene interpolymers which are then functionalized with a variety of electrophilic and nucleophilic reagents.
