One of the significant advantages of ROMP is the ability to control both the molecular weight and the polydispersity of the resulting polymer. Additionally, ROMP can tolerate a wide range of functional groups, making it a versatile method for synthesizing a variety of polymers. The use of well-defined catalysts also allows for precise control over the polymer architecture, enabling the synthesis of block copolymers, gradient copolymers, and other complex structures.
