SIMULATION OF CONFORMATIONAL AND HYDRODYNAMIC PROPERTIES OF DENDRIMER-LIKE POLYMERS UNDER FLOW

摘要: Dendrimers are highly and regular branched macromolecules that have attracted much attention due to their wide range of applications like catalysis, molecular recognition or drug delivery. Dendrimer-like star-branched polymers are a class of dendritic polymers, the first synthetic example dating back to 1995 (see the review [1] on the topic). These polymers exhibit molecular features similar to those of regular dendrimers, such as the presence of a central core, a precise number of branching points and many terminal functions. However, branches of regular dendrimers comprise a few atoms whereas dendrimer-like polymers present macromolecular chains between their branching junctions, as illustrated in the following sketch:We show the dependence of the radius of gyration and the intrinsic viscosity on the number of generations as well as the expected shear flow behaviour of dendrimer-like polymer dilute …
