“Studying Abnormal Viscosity Behavior in Dilute Oligomer Solutions by SEC and Rheology” by Andrë M. Striegel and David B. Alward; J. Liq. Chrom. & Rel. Technol.®, 25(13–15), pp. 2003–2022 (2002).

In this paper, a quantitative error in the calculation of the intrinsic viscosities, [η]_w, led to errors in Tables 1 and 2. The correct versions of the tables follow:

Table 1. Intrinsic viscosity of oligomer solutions in DMAc/0.5% LiCl at 35°C

Table 2. Intrinsic viscosity of oligomer solutions in TCB at 135°C

Sample	Solution concentration(mg/mL)	Injected volume(μL)	Injected mass(mg)	[η]w(dL/g)
PE 170	5.00	300	1.50	−0.0020
PE 282	5.00	300	1.50	−0.0036
PS 162	49.20	300	14.76	−0.0017

These errors do not affect the general observation of a negative viscosity effect in dilute solutions of styrene in DMAc/LiCl at 35°C, or of PS 162 and PE 170 in TCB at 135°C. Likewise, they also do not change the mechanism through which this behavior was explained. The stated concentration dependence of the effect, which was due the calculation error mentioned above, is obviously incorrect. The negative viscosity effect is observed to be concentration‐independent.

The authors apologize for this mistake and for any confusion that may have resulted therefrom.
