Temperature effects Inclusion polymerization

Molecular motions are much smaller in channels than in solution at the same temperature. This indicates that the polymerization may proceed slowly. But the neighboring monomers are located very near, suggesting that the reaction may proceed rapidly. This is how the reversed effects work during the propagation reaction. It is known that inclusion polymerization smoothly occurs at low temperatures in the chaimels of urea, thiourea, and perhydrotriphenylene. However, in the case of steroidal hosts, we observed a deerease in polymerization rates. For example. in one case, the polymerization reached a saturated state after 1 month. 

Miyata and Takemoto found that deoxycholic acid (DCA) and apocholic acid could be used as host molecules for inclusion polymerization of butadienes [75-83]. They reported the living nature of the polymerization, the effects of cocrystallized agents on the yields, and the increase in melting temperature after polymerization. In DCA, polybutadiene was over 25% 1,2...
