Poly‐n‐Hexyl methacrylate. IV. Dilute solution properties by viscosity and light scattering

Abstract: Poly‐n‐hexyl methacrylate prepared by the emulsion technique was fractionated three times by the fractional precipitation procedure to obtain eight fractions. Relationships between viscosity‐ and weight‐average molecular weight were obtained in both an ideal solvent, isopropanol, and a nonideal solvent, methyl ethyl ketone. These relationships are represented by equations: The effect of the size of the pendant groups (‐methyl, ‐ethyl, n‐butyl and ‐n‐hexyl ester) on the degree of extension of macromolecules… Show more

“…Dilute solution properties (chain dimensions and intrinsic viscosity) of poly(methacrylates) have been investigated experimentally 13–18. These reports have looked at the dilute solution properties of a series of n ‐alkyl methacrylate homopolymers, such as the methyl, ethyl, butyl, hexyl, 2‐ethylbutyl, octyl, and lauryl structures, wherein the relationship between intrinsic viscosity, mean‐squared end‐to‐end distance, and molecular weight has been obtained by the use of light‐scattering and viscosity measurement techniques in good solvents as well as in various ideal (theta) solvents.…”
