Abstract
The template polymerization of methacrylic acid along atactic poly (2-vinylpyridine) was studied calorimetrically at various monomer concentrations from 0.1 to 9.0 M in DMF; the concentration of the P2VP template was fixed at 0.4 base M. Azobisisobutyronitrile and bis( p- tert-butylcyclohexyl)peroxydicarbonate were used as initiators at concentrations of 0.1 and 0.01 M, respectively. The temperature was 30°. The results could be well described by a generalized kinetic model in which the effect of preferential adsorption of monomer by the template, this adsorption being assumed to be of the Langmuir type, has been taken into account, i.e. the model incorporates propagation along the template not only by picking-up monomer from the surrounding solution (mechanism II) but also by zipping-up pre-adsorbed monomer (mechanism I).
