摘要：

The influence of the excluded volume on the intrinsic viscosity of linear and star-like polymers in dilute solution is reflected on the Mark-Houwink-Sakurada (MHS) parameters k and "a", A correlation between these parameters and the number of arms for star-like polybutadiene in different solvents is proposed. Also, for various linear polymers, a relation describing the decrease of parameter k with increasing "a", the proportionality coefficient being the unperturbed parameter k(theta), is established.
