J. Mater. Chem.,, 2009, 19, 8068–8071 (DOI: 10.1039/b918130j). Amendment published 23rd December 2009.

The text “(Aldrich, Mn ~340)” at the bottom of page 8068 should read:

“(the isocyanate oligomer used was poly[(phenyl isocyanate)-co-formaldehyde] with average M_n ~340 from Aldrich (372986))”

The Royal Society of Chemistry apologises for these errors and any consequent inconvenience to authors and readers.
