Additionally, other features of polymer characterisation are discussed such as the determination of molecular weight, polymer fractionation techniques, chemical and thermal stability, resin cure, oxidative stability, photopolymers, glass and other transitions, crystallinity, viscoelasticity, rheological properties, thermal properties, flammability testing, particle size analysis and the measurement of the mechanical, electrical and optical properties of polymers.

Based on the molecular orientational tilting of LCs, various structures have been suggested to vary voltages onto LCs and thus change optical properties [5,6]. Choi et al. fabricated a two-dimensional LC microlens array using a surface relief structure of ultraviolet (UV)-curable polymer [5]. The microlens array cell was made with indium tin oxide (TTO) glass substrates. One substrate had a specific surface relief structure of the photopolymer used and the other had only the ITO layer. 

In this chapter the properties of organic molecules which are potentially useful as archival digital optical memory media, mainly erasable media, will be described. The memory media which require wet development/fixing processes will not be mentioned. Photopolymers and photoresists are also beyond the scope of this chapter. 

An oriented photopolymer is a polymer where photomodification is initiated by irradiation with plane-polarized light and where the molecular configuration has a preferred orientation as a result of linear polarization. These polymers have optically anisotropic and other novel properties.
