Abstract:
A nucleation agent, 1,3,2,4‐dimethylbenzylidene sorbitol (DMBS), was used as a support for C2‐symmetric metallocene rac‐Me2Si2‐Me‐4‐Naph‐Ind]2ZrCl2. Propylene polymerization with the supported catalyst resulted in i‐PP polymers with granular morphology. The role of a catalyst support ensures a good dispersion of the nucleation agent in the formed i‐PP matrix. The employment of a nucleation agent as catalyst support provides a unique solution to in‐reactor compounding metallocenic i‐PP/nucleation agent compositions.
