Topology Evolution in Polymer Modification
A recent numerical method has opened new opportunities in multidimensional population balance modeling. Here, this method is applied to a full three-dimensional population balance model (PBM) describing branching topology evolution driven by chain end to backbone coupling. This process is typical for polymer modification reactions, e.g., in polyethylene, where initially linear polymer chains un...
متن کاملSynthesis of magnetically active interpenetrating polymer network for drug release
Interpenetrating polymer networks (IPN) were formed involving hydrophobic polybutyl acrylate (PBA) and hydrophilic poly hydroxyethyl acrylate (PHEA). PBA prepolymer was first formed in presence of ferric oxide nanoparticles (

متن کاملassessment of the efficiency of s.p.g.c refineries using network dea
data envelopment analysis (dea) is a powerful tool for measuring relative efficiency of organizational units referred to as decision making units (dmus). in most cases dmus have network structures with internal linking activities. traditional dea models, however, consider dmus as black boxes with no regard to their linking activities and therefore do not provide decision makers with the reasons...
Universal Cyclic Topology in Polymer Networks.
Polymer networks invariably possess topological defects: loops of different orders which have profound effects on network properties. Here, we demonstrate that all cyclic topologies are a universal function of a single dimensionless parameter characterizing the conditions for network formation. The theory is in excellent agreement with both experimental measurements of hydrogel loop fractions a...
