Group polymeric compounds

Formulas for polymeric compounds are for the repeat unit only and ignore the end groups. 

The bifunctional azo initiator can initiate a polymerization of a monomer A forming a polymeric compound containing at least one azo group in its main chain [Figure 1, Scheme (1)]. Naturally, the monomer A has to have suitable sites for reacting with the transformation site F. The azo-containing polymers obtained in Scheme... 

Silicones are a large group of compounds that include large polymers containing silicon. Depending on the formula and the degree of polymerization and cross-linking of the polymers, they may be slippery liquids, waxes, or rubbers. 

C) In the presence of a nucleophilic exomolecular agent such as H20, cysteine, amino acids, or amino groups, the nucleophilic agent is added to the o-quinone structure that evolves to a modified diphenol in position 5, which produces several polymeric compounds. 

Note 2 Mesogeuic groups occur in both low-molar-mass and polymeric compounds. 

Later, Tieke reported the UV- and y-irradiation polymerization of butadiene derivatives crystallized in perovskite-type layer structures [21,22]. He reported the solid-state polymerization of butadienes containing aminomethyl groups as pendant substituents that form layered perovskite halide salts to yield erythro-diisotactic 1,4-trans polymers. Interestingly, Tieke and his coworker determined the crystal structure of the polymerized compounds of some derivatives by X-ray diffraction [23,24]. From comparative X-ray studies of monomeric and polymeric crystals, a contraction of the lattice constant parallel to the polymer chain direction by approximately 8% is evident. Both the carboxylic acid and aminomethyl substituent groups are in an isotactic arrangement, resulting in diisotactic polymer chains. He also referred to the y-radiation polymerization of molecular crystals of the sorbic acid derivatives with a long alkyl chain as the N-substituent [25]. More recently, Schlitter and Beck reported the solid-state polymerization of lithium sorbate [26]. However, the details of topochemical polymerization of 1,3-diene monomers were not revealed until very recently. 

Many group 13 compounds have been prepared with porphyrins. The majority of these compounds were created to serve as models for the active sites of enzymes, such as cytochrome c oxidase. Additionally, the gallium compounds are more robust than their iron counterparts. To a much lesser extent the Por-AlX compounds are used as oxirane polymerization catalysts [8]. 

Stereocomplexes are a special group of compounds which can be obtained as a result of template polymerization and stereocomplex formation, described many years...
