Book excerpt: To predict the effect of reaction temperature and the inert gas feed rate on condensation polymerization of unsaturated polyester between maleic anhydride and propylene glycol. The developed dynamic model consisted of three parts, the reactor model, the kinetic model and the mass transfer model. The simulated result was verified by comparing to the process identification from the experimental data. The comparison of the simulation and experiment gave a satisfaction and the developed model was valid. The simulation illustrated that the effect of reaction temperature and the inert gas flow were more complicate to the process parameters because of the changing in the bulk liquid properties during polymerization. Both of reaction temperature and the inert gas flow rate were influence to the process parameters via the exact and diverting paths. Increasing of reaction temperature would increase the rate of condensation polymerization by enhancement of rate constant. Increasing of inert gas flow rate would increase the polymerization rate by increasing of specific interfacial area for mass transfer. In both two cases, the reaction time should decrease.

Book excerpt: This study explores the best suitable internals and various feed configurations of a reactive distillation process for unsaturated polyester synthesis. Multi-product simulations were performed to find the operational parameters for producing different grades of polyester in the same equipment. The product transition time during product changeover is determined for various configurations and product grades. The selection criteria for the best configuration are the minimum requirements of volume and energy to produce 100 ktpy polyesters. The results of the rigorous simulations carried out in Aspen Custom Modeler show that the best configurations employ the reactive stripping section as a packed or trayed bubble column, and the reactive rectifying section as a packed column. With respect to the feed configuration, the feeding of monoesters to the RD column significantly intensifies the polyester process as compared to an anhydrous reactant fed directly to the column. Moreover, the product transition time in this configuration is also significantly reduced as compared to the other configurations.

Available in PDF, EPUB and Kindle. Book excerpt: Unsaturated polyester resins (UPR) and vinyl ester resins (VER) are among the most commercially important thermosetting matrix materials for composites. Although comparatively low cost, their technological performance is suitable for a wide range of applications, such as fiber-reinforced plastics, artificial marble or onyx, polymer concrete, or gel coats. The main areas of UPR consumption include the wind energy, marine, pipe and tank, transportation, and construction industries. This chapter discusses basic UPR and VER chemistry and technology of manufacturing, and consequent applications. Some important properties and performance characteristics are discussed, such as shrinkage behavior, flame retardance, and property modification by nanoparticles. Also briefly introduced and described are the practical aspects of UPR and VER processing, with special emphasis on the most widely used technological approaches, such as hand and spray layup, resin infusion, resin transfer molding, sheet and bulk molding, pultrusion, winding, and centrifugal casting.
