✦ Synopsis

The synthesis of poly(2-acryloyloxyethyl methacrylate) has been performed followed by its polymerization. The kinetics of photochemically initiated template polymerization resulting in a ladder polymer has been examined. Global reaction rate constants within 293È313 K, global activation energy, activation entropy and initiation rate have been determined. It has been found that in comparison with a conventional polymerization process of methyl methacrylate, the template process is characterized by reduced activation energy and entropy. It has been observed that in the polymerization of multimonomer (when monomer units are linked with the template by covalent bonds), there are similar regular relationships to those in the template polymerization of methyl methacrylate, where the only forces acting between the template and the growing macroradical are intermolecular.
