Paper Abstract

We describe the diffraction properties of organic nanoparticle-dispersed photopolymers in which hyperbranched polymers (HBPs) act as transporting organic nanoparticles that increase the refractive-index contrast of a hologram. We prepared HBPs by the living radical vinyl polymerization of inimers under ultraviolet-light illumination. Such synthesized HBPs are easy to disperse into monomers without any aggregation, so that samples with good optical quality are available. We investigate the role of HBPs in the recording process for two different types of photopolymers capable of radical polymerization and cationic ring-opening polymerization. We also evaluate the effect of HBP dispersion on recording sensitivities and polymerization shrinkage.
