초록

Poly(n-hexyl-(S)-3-methylpentylsilane) aggregates confined in microcapsules to keep the aggregation number and ranging in average polymer mass in a microcapsule from $2{\Box}10^{-16}\;to\;2{\Box}10^{-14}g$. were studied by circular dichroism measurements in ethanol (a non solvent) and tetrahydrofuran (an associative solvent at low temperature) at varioustemperatures. The size of each aggregate did not affect the optical activity because the circular dichroism was proportional to the aggregation number at the same condition. Moreover, the circular dichroism appreciably reflected the prepared method, i.e. temperature and solvent.
