“…At a certain amount of NС in the composition, this fact can be a result of microphase separation of the polymerizable medium and porous structure formation in the bulk polymer [2,5,13]. For example, self-formation of a nanoporous polymeric structure was obtained during the curing of the photopolymerizable composite based on an oligo (ester acrylate) OСM-2 in the presence of more than 25 wt.% of methanol [13]. Providing heterogeneous distribution of the neutral component, so that there are areas with increased and decreased concentration of NC, enables creation of heterogeneous polymeric materials with nanoporous and monolithic areas.…”

“…Pores in the bulk of the final polymer are not observed if concentration of such NC is less than 10 wt.% [13]. Hence, formation of the porous structure requires more than 25 wt.% of a NC fraction, while the polymerizable medium viscosity should not be too high, i.e., the polymer content should not exceed, for example, 10 wt.% (Fig.…”

“…Note, that the critical concentration of the porous structure formation in the polymer bulk is specific for different NC and PPC [13]. For example, in the PPC based on OCM-2 the pores formation is observed, if the concentration of dinonyl phthalate (additive) is more than 10 wt.%, but this value is about 4 wt.% for hexane.…”

“…Porous polymeric materials can be self-formed due to the phase separation of the components of the polymerizable medium during the curing process [2,3,[13][14][15][16]. Previously, we have observed and studied the effect of pore formation in the photopolymerizable composites (PPC) based on oligo (ester acrylates) in the presence of non-polymerizable neutral components (NC) [13].…”

“…Previously, we have observed and studied the effect of pore formation in the photopolymerizable composites (PPC) based on oligo (ester acrylates) in the presence of non-polymerizable neutral components (NC) [13]. The specificity of these media is involved in the formation of a three-dimensional cross-linked polymer being partially compatible with NC as a result of oligo (ester acrylates) polymerization.…”

The possibility to form polymeric materials with heterogeneously distributed nanopores from a photopolymerizable composite containing a non-polymerizable additive is studied. The diffusive redistribution of the composite components during photopolymerization by non-uniform initiation is simulated. The interlaced areas of the nanoporous structure and the homogeneous monolithic polymer are shown to be formed in the polymer bulk under the acting of the radiation with a periodic distribution of intensity. The influence of the initial concentration of the neutral component in the composite, the diffusion parameters of the polymerizable medium, and parameters of actinic radiation on the size of the nanoporous and monolithic areas are determined. The obtained computer simulation results are experimentally verified.

Novel porous polymers with 4‐ethoxy‐3,6‐di‐tert‐butyl‐o‐benzoquinone grafted to the porous surface have been prepared via the secondary functionalization of porous polymer monoliths obtained by the photopolymerization of oligo(carbonate dimethacrylate) and hydroxyethyl methacrylate in methanol solution. These quinone‐functionalized polymers have been applied for the synthesis of triphenylantimony(V) catecholate‐containing polymers by the oxidative addition reaction of quinone moieties with SbPh3. The obtained antimony‐containing porous polymeric material is able to reversibly bind molecular oxygen in nearly quantitative yield. The rate of molecular oxygen sorption is 900 times higher for the porous material than that for the same film material and comparable with the process rate in solution.

The possibility of one‐stage formation of planar light‐guiding structures from photopolymerizable compositions with a neutral component by the photolithographic method is investigated. It is shown that the required profile of the refractive index in the light‐guide, which is a polymeric core surrounded by a low‐refracting damper of the same material with a higher concentration of the neutral component, can be formed due to diffusion processes stimulated by nonuniform distribution of actinic radiation intensity. The results of numerical modeling and experiments on the optical formation of stable light‐guiding 2D‐structures with a volume distribution of the refractive index in the polymer layer are presented.
