The effect of post heat-treatment on the spectral properties of photopolymer reflection holograms scheme has been studied. It has been established that holograms with protective film retain a high diffraction efficiency of ∼ 90% and do not have additional shrinkage during heat treatment for several days at a temperature of 80–90°C. The holograms without a protective film, removed after exposition, when heated in the temperature range of 40–110°C, show effective shrinkage up to 17% without compromising diffraction efficiency. Addiction the degree of shrinkage from the time of keeping the hologram at a given temperature is described by the function biexponential growth with saturation. The parameters of the approximating function are calculated. The characteristic shrinkage times in the temperature range of 40–110°C decrease from hours to minutes for fast components and from tens of days to tens of minutes for the slow component. Effect large shift of spectral response was used to create color-separated holograms. Color-separated holograms were obtained in two ways: two-layer version with shrinkage of one of the layers, single-layer version using photoresistive pattern and subsequent shrinkage.

The effect of post heat-treatment on the spectral properties of photopolymer reflection holograms scheme has been studied. It has been established that holograms with protective film retain a high diffraction efficiency of ~ 90% and do not have additional shrinkage during heat treatment for several days at a temperature of 80-90oC. The holograms without a protective film, removed after exposition, when heated in the temperature range of 40-110oC, show effective shrinkage up to 17% without compromising diffraction efficiency.

“…NMR proves to be a powerful tool to probe these heterogeneities at the molecular level. Thiol–ene polymerizations combine both chain-growth and step-growth mechanisms, enabling the systematic variation of dynamic heterogeneity through the stoichiometry of the polymerization mixture [ 21 , 22 , 23 , 24 , 25 , 26 , 27 , 28 ], which can be used to control the relationship between the cure temperature and the final T g . We prepared a series of high-T g materials, in which the heterogeneity was modulated by the reacting mixtures of the aromatic monomer 1,3,5-benzenetrithiol (BTT) and tricyclodecane dimethanol diacrylate (TCDDA) with differing ratios of the reactive functional groups.…”

NMR spectroscopy continues to provide important molecular level details of dynamics in different polymer materials, ranging from rubbers to highly crosslinked composites. It has been argued that thermoset polymers containing dynamic and chemical heterogeneities can be fully cured at temperatures well below the final glass transition temperature (Tg). In this paper, we described the use of static solid-state 1H NMR spectroscopy to measure the activation of different chain dynamics as a function of temperature. Near Tg, increasing polymer segmental chain fluctuations lead to dynamic averaging of the local homonuclear proton-proton (1H-1H) dipolar couplings, as reflected in the reduction of the NMR line shape second moment (M2) when motions are faster than the magnitude of the dipolar coupling. In general, for polymer systems, distributions in the dynamic correlation times are commonly expected. To help identify the limitations and pitfalls of M2 analyses, the impact of activation energy or, equivalently, correlation time distributions, on the analysis of 1H NMR M2 temperature variations is explored. It is shown by using normalized reference curves that the distributions in dynamic activation energies can be measured from the M2 temperature behavior. An example of the M2 analysis for a series of thermosetting polymers with systematically varied dynamic heterogeneity is presented and discussed.
