Other types of hypercrosslinked organic polymers

Several other types of hypercrosslinked networks can be found in scientific publications, although their authors did not recognize the unique nature of polymeric products obtained, and did not test their swelling in 

In this case, formation of a network of covalent bonds between the linear chains is not necessary for the generation and maintenance of 

compared to linear PIMs, 3D polymeric structures usually display higher values of specific surface area. Thus, a single-phase cyclotricatechy-lene-based network polymer with contorted bowl-shaped repeating units as 

The polymer was tested for storage of hydrogen. The loading capacity proved to be not very high, 1.5-1.7% at 77 K and 5-10 atm, which, still, is comparable with that of activated carbons and carbon nanotubes. 

Highly rigid and contorted aromatic spirobisindane-based linkers were shown to ensure a space-inefficient packing of phthalocyanine macrocycles, giving polymer networks [269] with gratifyingly high surface areas (500-1000 m /g) and interconnected nanopores of diameters in the range 0.6—0.8 nm.
