Relationship between molecular weight and viscosity for polydispersed poly(n-docosyl acrylate)

Abstract

The Mark-Houwink-Sakurada (MHS) relation for polydispersed poly(n-docosyl acrylate) was established from gel permeation chromatography (GPC) and intrinsic viscosity measurements. Average K and α for polydispersed comb-like poly(n-docosyl acrylate) in telrahydrofuran at 35°C, were 4.95 × 10-5 dl g-1and 0.738, respectively. The X-ray diffraction peak of poly(n-docosyl acrylate) at about 2θ=22° corresponded to the typical spacing of hexagonal packing of long alkyl side chains of the acrylate polymer.
