Macroporous Poly(N‐isopropylamide‐co‐acrylamide) Hydrogels Prepared by Two‐Step Polymerization for Drug Delivery Applications
Authors: Huo D. , Yang J. , Hou C. , Yang M. 
Published: October 2010

AbstractMacroporous poly(N‐isopropylamide‐co‐acrylamide) [P(NIPAAm‐co‐AAm)] hydrogels were successfully prepared by a two‐step polymerization method. The initial polymerization was carried out at 18 °C with different duration, followed by freezing polymerization at –18 °C for 24 h. The results showed that the immediate performance of freezing polymerization played a dominant role in the final properties of the P(NIPAAm‐co‐AAm) hydrogels. The thermoresponsive rate and mechanical strength of the hydrogels were drastically changed by freezing the reaction mixture after 3 min of the first polymerization (PNA‐3). Scanning electron microscopy (SEM) studies revealed that the hydrogel frozen after 3 min exhibited the most highly interconnected porous structures and the largest pore size. These open pore structures were very useful to accelerate the responsive rate of the hydrogels. In vitro BSA (bovine serum albumin) release from the hydrogel PNA‐3 exhibited relatively small initial burst release followed by a steady release. Such results demonstrated that the P(NIPAAm‐co‐AAm) hydrogels frozen before gelation have the potential to be applicated for delivering proteins.
Suspension Polymerization Processes
Authors: Brooks B. 
Published: October 2010

AbstractIndustrial suspension polymerization usually proceeds by a free‐radical mechanism to produce polymer beads. The size distribution of the polymer beads is often similar to that of the polymerizing drops in the reactor. That distribution is determined by the operating mechanisms of drop breakage and drop coalescence. Consequently, the value of the Reynolds number is significant and a potential change in flow regime must be considered in reactor scale‐up. The choice of suspending agent, which can be a water‐miscible polymer or a finely divided particulate solid, can affect both the drop size and the properties of the final product. High monomer conversions are attainable but reaction kinetics can be affected by increases in drop viscosity during the polymerization. Drop mixing, which sometimes takes place, can be slow, so that non‐uniformity occurs in the final product. With copolymerization, complications can arise if the initiator, or one of the monomers, is partially soluble in the continuous phase. Adverse environmental impact of suspension polymerization can be avoided by cleaning and/or recycling the continuous phase when it leaves the reactor.
Melt Index Prediction Based on Adaptive Particle Swarm Optimization Algorithm‐Optimized Radial Basis Function Neural Networks
Authors: Zhao C. , Liu X. , Ding F. 
Published: October 2010

AbstractReliable estimation of the melt index (MI) is crucial in the quality control of practical propylene polymerization (PP) processes. In this paper, a novel predictive neural network system, combining the particle swarm optimization (PSO) algorithm and radial‐basis function neural networks (RBFN), is presented to infer MI from real PP process variables, where the PSO algorithm dynamically constructs the RBFN structure and parameters and a new adaptive PSO (APSO) algorithm, which adjusts the algorithm behavior based on evolution information of swarms, further accelerates the convergence speed. Principle component analysis is applied to select the most relevant process features and to reduce the number of input variables in the model. A detailed comparison between PSO, APSO and the gradient descent algorithm is carried out using historical data from a real plant.
Simulation of Polymerization Kinetics and Molecular Weight Development in the Microwave‐Activated Emulsion Polymerization of Styrene using EMULPOLY®
Authors: Jaramillo‐Soto G. , Ramírez‐Cupido M. , Tenorio‐López J. A. , Vivaldo‐Lima E. , Penlidis A. 
Published: October 2010

AbstractThe emulsion polymerization of styrene, activated by microwave irradiation and conductive heating, was modeled using the EMULPOLY® simulation package of the University of Waterloo. Microwave‐activated initiation was modeled as adding a hypothetical second initiator. The kinetic rate constants and model parameters used in the simulation were taken from the simulator database, with the exception of the microwave activation constant, kir, and the efficiency, fr, of the hypothetical initiator. Model predictions of conversion, number‐ and weight‐average molecular weights, for microwave‐ and thermally activated systems agreed well with the experimental data reported in the literature. The effects of microwave power supplied to the system on monomer conversion, molecular weight values and particle number were analyzed.
Copolymerization Kinetics of Styrene and Divinylbenzene in the Presence of S‐Thiobenzoyl Thioglycolic Acid as RAFT Agent
Authors: Roa‐Luna M. , Jaramillo‐Soto G. , Castañeda‐Flores P. V. , Vivaldo‐Lima E. 
Published: October 2010

AbstractAn experimental study on the kinetics of the reversible addition‐fragmentation chain transfer (RAFT) copolymerization of styrene (STY) and divinylbenzene (DVB) is presented. The experiments were carried out in bulk from a mixture of monomers, S‐thiobenzoyl thioglycolic acid as RAFT agent, and the initiator dibenzoyl peroxide (BPO) at 80 °C. The effect of RAFT agent concentration, including the case without RAFT controller, on polymerization rate, molecular weight development, gel fraction, and swelling index was analyzed.
Polymerization Online Monitoring
Authors: Frauendorfer E. , Wolf A. , Hergeth W.‐D. 
Published: October 2010

AbstractOnline monitoring of polymerization reactions is not only important due to the high exothermic nature of most polymerization systems; the data gained also provides information on product composition and quality and control possibilities thereof. Many inline and online methods are still in development and are better suited for application on the laboratory or pilot‐plant scale. Industrial polymerization plant environments pose additional technical and financial challenges and constraints for the use of such systems. Available methods and current developments are reviewed with regard to their practicability and usefulness under these aspects.
From Molecular to Plant‐Scale Modeling of Polymerization Processes: A Digital High‐Pressure Low‐Density Polyethylene Production Paradigm
Authors: Kiparissides C. , Krallis A. , Meimaroglou D. , Pladis P. , Baltsas A. 
Published: October 2010

AbstractA generalized multiscale modeling framework is described for the digital simulation of a high‐pressure low‐density polyethylene (LDPE) tubular reactor. According to the proposed modeling approach, various models describing the complex physical and chemical phenomena at different length and time scales are linked together to assess the effects of reactor operating conditions on the molecular and rheological behavior of LDPE. The molecular properties of LDPE are determined by employing a comprehensive kinetic scheme. On the basis of the postulated kinetic mechanism, detailed population balance equations (PBEs) are derived describing the conservation of the various macromolecular polymer chains. A review of the potential methods for solving the governing PBEs is presented. In addition, a novel kinetic/topology Monte Carlo method to calculate the molecular and topological properties of the highly branched polymer chains and an advanced rheological model for the calculation of the viscoelastic properties of branched polymers in terms of their respective molecular and topological properties are described.
