| Abstract: | Using poly( -norbornenyl polystyrene) as a model we studied the conformation and the structure of branched polymer chains each of whose backbone constitutive units bear a branch. The parameters taken into account are: the polymerisation degree of the backbone, the molar mass of the branches and the solution concentration. The effect of the global conformation of these polymacromonomers, either spherically or cylindrically (vermiform) symmetric, is considered. The compactness of the polymer constitutive unit distribution, the branches and the backbone conformations are considered as functions of the first two parameters above. Significant results are obtained on all of these three points.Received: 24 May 2004, Published online: 21 September 2004PACS: 61.12.Ex Neutron scattering - 61.41. + e Polymers, elastomers, and plastics - 61.46. + w Nanoscale materials: clusters, nanoparticles, nanotubes, and nanocrystals |
