  • Grafted polymers
    Patent number: 11046801
    Abstract: A process is provided for grafting CRP synthesized polymers to dienes and polyolefins in the presence of a CRP controlling agent. Chain scission is minimal. Graft yield can be high and is proportional to the amount of CRP controlling agent added. The grafting process can be carried out either in a molten phase, preferably by reactive extrusion, or in a solvent-based process. The process provides novel families of grafted polyolefins and dienes, which show promising applications as new materials and as additives in the polymer industry.
