Abstract
Crosslinking of polymers with dipoles can be followed by means of dielectric, pyroelectric, and in situ electro-optic measurements. All three techniques provide similar insights as to the cross-linking process. In addition, electro-optic measurements allow for the determination of the resulting optical nonlinearity. After crosslinking is completed the polymer behaves like a side-chain polymer. In addition, photoinduced poling of an already cross-linked dipolar polymer network is demonstrated.
