Synthesis and Radical Polymerization of Adamantyl Methacrylate Monomers Having Hemiacetal Moieties
The design strategy and synthesis of bulky, hydrophobic, and thermally, stable adamantyl methacrylate monomers with attached hydrophilic and acid labile three different types of alkyl (1 degrees, 2 degrees, 3 degrees) hemiacetal side groups are described. Free radical polymerizations of the obtained monomers furnished the desired polymers with high molecular weights. The properties such its thermal stability, moisture stability, and acid sensitivity of the obtained adamantyl hemiacetal ester homopolymers were evaluated which showed strong structure-property dependence. The bond dissociation enthalpy of the obtained polymers depended oil the electronic effects of the type of pendant hemiacetal ester side groups.
