    Notes: A restricted diffusion model is developed to study the immobilization of enzyme in porous solid supports. Simulation studies have been carried out for various combinations of process variables and parameters of the immobilization system. The model has also been used to develop a method for estimating the intrinsic rate constant of immobilization when enzyme diffusion into the support is restricted. Results of experiments in which glucose oxidase was immobilized in porous glass supports are consistent with model simulations.

    Notes: The oxidation of CO over aluminum-supported Ag was studied at 147°C using transient experiments. Long-time-scale dynamics were observed that could not be explained by previously postulated kinetic mechanisms for this reaction system. A model is presented with kinetic parameters estimated from steady state and transient data that is able to reproduce a variety of cycled feed stream experiments. The model incorporates a slow reversible step which forms an adsorbed oxygen species that blocks reaction sites.

    Description / Table of Contents: Durch die Synthese von cyclischen Acrylaten wurde eine Reihe von Monomeren erhalten, die hohe Reaktivitäten der Copolymerisation bei gleichzeitiger Fähigkeit zur radikalischen Ringöffnungspolymerisation aufweisen. Sie wurden polymerisiert, um einen Pyruvatester in die Polymerkette einzuführen. Eine Reihe von Spiromethylencyclohexadienen wurde hergestellt, um neben der Carbonylgruppe und gespannten Ringen weitere Gruppen zu finden, die die radikalische Ringöffnungspolymerisation fördern. Bei ihrer Polymerisation wurden Polymere mit einer p-Phenylengruppe in der Kette erhalten.
    Notes: In order to find a series of monomers with high reactivities in copolymerization and still undergo free radical ringopening polymerization, a series of cyclic acrylates were synthesized and polymerized to insert a pyruvate ester into the backbone of the polymer. In order to discover groups other than the carbonyl groups and strained rings that would promote free radical ring-opening polymerization, a series of spiro methylenecyclohexadienes were prepared and polymerized to give a polymer with a p-phenylene group in the backbone.
