15. Linear PMMA would not normally be expected to be an appropriate calibration standard for the branched OEGMA homopolymers. However, we have observed surprisingly good agreement between PMMA standards and OEGMA homopolymers of similar molecular weight prepared by group transfer polymerization [Bütün, V.; Vamvakaki, M.; Billingham, N. C.; Armes, S. P. Polymer, 2000, 41, 3173].
