Influence of Cyclodextrin and Temperature on the Kinetics of Free Radical Polymerization of N-Adamantylacrylamide in Water

N‐Adamantylacrylamide (3) was complexed with randomly methylated β‐cyclodextrin (RAMEB) forming the water‐soluble host–guest monomer‐complex 3a. A 1:1 complex stoichiometry was proven by NMR titration (Job's method). We investigated the free radical polymerization of the complex 3a using the water‐soluble azoinitiator 2,2′‐azobis[2‐(2‐imidazolin‐2‐yl)‐propane]dihydrochloride (VA044) at different temperatures. We observed that, below Tcrit a solution polymerization of 3a takes place. Above Tcrit, a precipitation mechanism leads to an increase in the relative polymerization rate.
