Crosslinked Polymer

Chemical crosslinker polymer gels were synthesized in situ polymerization of monomers in solvents with crosslinkers. Results showed that the solvent content of the polymer gels depended on the types of solvents and polymers as well as the crosslinkers. The adsorption ability to aromatic organic molecules of the polymer gels was measured by treating tryptophan solution containing phenol and pyrene aqueous solution. The aromatic compounds can be removed completely and no further pollution to the original solutions.

The cross-linked polymer gel systems are being used increasingly to redirect or modify reservoir fluid movement in the vicinity of injection wells for the purpose of permeability/profile modification job in the oil field due to their high temperature stability and capability to provide rigid gel having high mechanical strength. In this study, a partially hydrolyzed polyacrylamide-hexamine-hydroquinonegel is used for the development of polymer gel system. The experimental investigation demonstrates that the gelation time varies with polymer and crosslinker concentration and the temperature. The mathematical model is developed with the help of gelation kinetics of polymer gel and using Arrhenius equation, which relates the gelation time with polymer, crosslinker concentrations, and temperature. The developed model is solved with the help of multivariate regression method. It is observed in this study that the theoretical values of gelation time have good agreement with the experimental values.

Interactions of polymer and solvent in a highly chemical crosslinked polystyrene (PS) and polymethyl acrylate (PMA) gels are investigated. Crystal thermo of the benzene in PS-benzene gels were analyzed using differential scanning calorimeter (DSC). It was noted that benzene molecules in the gels can be categorized into three types, which is free benzene, weak bonded benzene and strong bonded benzene. In average, one PS structure unit interacted with three benzene molecules in the gel system. The conformation of dichloroethane (DCE) in PMA-DCE gels was studied using Fourier transfer infrared (FTIR). In PMA-DCE gels, DCE molecule bonded with PMA chains in a trans mode through a hydrogen bond. And the amount of trans DCE molecules increased with the increase in concentration of PMA in the gel system.

Network Morphology

The rheological and mechanical properties of crosslinked polymer gels arise from the structure of the gel network. In turn, the structure of the gel network results from: thermodynamically determined interactions between the polymer chain segments, the interactions of the crosslinking metal ion with the polymer, and the deformation history of the network. Interpretations of mechanical and rheological measurements on polymer gels invariably begin with a conceptual model of,the microstructure of the gel network derived from polymer kinetic theory. In the present work, we use freeze-etch replication TEM to image the polymer network morphology of titanium crosslinked hydroxypropyl guars in an attempt to directly relate macroscopic phenomena with network structure.
