37. A closer analysis of the SANS data showed that in addition to monomers and dimers a small amount of larger aggregates with a maximum diameter up to 11 nm is also present in solution under these conditions.
38. Even though for such small particles (with size distribution) this analysis is accompanied by a relatively large error, coil-like or rodlike aggregate shapes can clearly be excluded. However, a homogeneous sphere structure might also be in accordance with experimental data within the experimental error range.
