Cyclic of poly

Table 1.5 summarizes the studies on cyclics of poly(di-methyl siloxane) and derivatives, and Table 1.6, those of other polymers. In these tables, refers to the molar cyclization equilibrium constant and RIS, to the rotational isomeric state scheme to analyze chain conformations. 

Comprehensive reviews of the history, chemistry, and physical chemistry of rotaxanes and the related architecture, the catenanes, have been published [115-120], Joyce et al. [121] reported a molecular modeling study of cyclics of poly(dimethylsiloxane) to imderstand the energetics of the threading process of linear chains with particular reference to rotaxanes. Of relevance is also the exhaustive review by Wenz [122] on the role of cyclodextrins in the building of supramolecular structures. Cyclodextrins are cyclics of D-glucose, with a-1,4 linkages. The common ones are a,/3, y-cyclodextrins, with 6, 7, and 8 D-glucose units, respectively. 

TABLE 1.5. Cyclics of poly(dimethyl siloxane) and its derivatives. 

Considerable information on polysiloxane cyclics is available in reviews of cyclic polymers in general. Considerable attention has been paid to cyclics of poly(dimethylsiloxane), poly(phenylmethylsiloxane), and...
