Abstract

PMMA blends were
synthesized through atom transfer radical polymerization (ATRP) method under at
different concentration ratios. The viscosity characteristics of the structure
were investigated to determine the behaviour of macromolecules in blends. The viscosity
characterization of the nanoparticles was determined to explain the molecular
structure and interactions. The intrinsic viscosity of the blend was calculated
with three different models including Huggins, Kraemer, and Rao. All blends
were performed to understand the effect of additives concentration on molecular
conformations and the intrinsic viscosity of the polymers. The voluminosity (V_E)
and the shape factor (υ) were calculated for the blends to understand the
miscibility behaviour. From experimental results, it was observed that the
intrinsic viscosity was increased with the increase in the amount of substance
and the solubility of the system in solution.
