Abstract
It is shown that the interpolymer complex of poly(silicic acid) and poly(ethylene glycol) formed in the organic solvent benzene is thermodynamically more stable than the corresponding complex with PMMA. Therefore, poly(silicic acid) prepared via template polycondensation conducted in the presence of poly(ethylene glycol) contains a smaller amount of defects (branches and crosslinks) than the same polymer obtained in the presence of PMMA. To provide evidence for the interaction between poly(silicic acid) and PMMA, the dynamic light-scattering method with the use of “invisible” macromolecules has been applied for the first time.
