The paper is concerned with the conformational characteristics of oligo- an
d polyacrylonitrile in dilute solution as evidenced by gel permeation chrom
atography (GPC) and viscometric data. The effects of chain ends and chain s
tiffness on the Mark-Houwink dependencies are discussed for a large domain
of molecular weights. (C) 1998 Elsevier Science Ltd. All rights reserved.
