Recent Advancements in the Synthesis of Functional Polyolefins by Non-Bridged Half-Titanocenes

Molecules
Polyolefins are used widely due to their benefits such as being lightweight, chemical inertness, low cost, tunable properties, and easy processability. However, their nonpolar nature significantly limits their high-end applications.
