DILUTE SOLUTION PROPERTIES OF POLY (N-OCTYL METHACRYLATE). II
Abstract
Phase separation studies were carried out to find another theta solvent for poly(n-octyl methacrylate). Isobutyl alcohol at 19.7 C was found satisfactory for this purpose. This polymer, under unperturbed conditions, s more extended than poly(2-ethylbutyl methacrylate). However, the degree of chain extension is still less than that of poly(n-hexyl methacrylate). Comparison of light scattering results from dissymmetry obtained in previous work with those obtained from more complete angular studies confirms the earlier results, with rather inor exceptions. However, dimensions obtained from the Zimm plots are considerably greater than those from dissymmetry. This work gives some indication that the fractions are not very homogeneous with respect to molecular weight. (Author)
