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 θ , is established.
