Element organic polymer

In addition to polystyrene, several other polymers have been provided with the hypercrosslinked structure, and, in addition to the postcrosslinking of preformed polymeric chains, other synthetic approaches to hypercrosslinked open networks have been developed, including the direct polymerization and polycondensation of appropriate monomers or co-monomers. The recently developed metal-organic frameworks and covalent organic frameworks constitute three-dimensional coordination and element-organic polymers with an unusually h%h free volume they fit into the new and rapidly growing class of hypercrosslinked network materials as well. [Pg.667]

This review concerns the mesomorphic state of the element-organic polymers. In this connection, a question arises, what is the reason for separating the mesophase element-organic polymers into a special class. To answer this questicm, it is necessary to consider the contemporary dassifrcation of the mesomorphic states in general and mesomorj ic states of pofymers in particular. [Pg.131]

The most rigid chains are those of ladder polyorganosilsesquioxanes. Together with esters of cellulose, these polymers are an example of the lyotropic liquid crystalline system which is formed by semirigid macromolecules. ITie structure of their solid mesophasese has not been studied sufficiently enough, therefore, at present it is not clear whether it can be considered as a disordered crystal or as a liquid crystalline phase. Further study of the structure of the mesophases in element-organic polymers and low molecular substances would undoubtedly be very useful for the development of the concept of disordered crystals. [Pg.177]
