Synthesis of Monolithic Supports

The choice of a suitable initiator represents an important step in creating a well-defined polymerization system in terms of initiation efficiency and control 

The porogenic solvents are chosen for optimal formation of both small and large pores. A combination of both small and large pores provides both high surface area for functionalization and low backpressure with optimal flow through the support, respectively. There are two basic types of ROMP-based supports synthesized today those from NBE derivatives, and those from COE-based monomers. The COE-based supports are not as common and are less studied, but they provide the oxidative stability that is necessary in some applications through having sec-allylic carbons compared to NBE-based materials rerr-allylic carbons [127,128].
