The main contents were as follows: Two-stage process has been developed to synthesize the macromonomer through surface-modification of silica with polymerizable vinyl groups.

The monomers with vinyl groups at two ends of the main chain after exposed to linearly polarized ultraviolet (LPUV) light can induce homogeneous alignment of liquid crystal molecules.

The types, synthesis processes and properties of polyphenylene oxide (PPO) with some functional groups such as bromine, vinyl, amide and so on are reviewed. Its application is also expected.
