MODIFICATION functional polysiloxanes, synthesis

Rutnakompituk, M. Modification of epoxy-novolac resins with polysiloxane containing nitrile functional groups synthesis and characterization. Eur. Polym. J.. 2005, 41, 1043. 

Polysiloxanes gain more and more interest in recent years due to their excellent chemical and physical properties, such as thermal stability, hydrophobicity or electrical resistance (1). One synthesis route towards linear polymers is the ROP of cyclic monomers such as hexamethylcyclotrisiloxane (D3) (2). The functionalization of the substituents on the silicon atom in the polymer is performed via the modification of the cyclic monomers. Especially vinylic side groups are often introduced into the polymer backbone since they are active groups for cross-linking of polysiloxanes to three dimensional networks such as silicone elastomers (3).
