The degradation of novel biodegradable segmented polyurethanes was investigated with a view to determining the cleavage points within the polymer backbones targeted by the enzyme chymotrypsin. While the materials were developed with specific enzyme cleavage sites designed into the polymer chains, the nature of their degradation had not yet been determined.(More)
Fiber-optic quasielastic light scattering and oscillatory shear rheology are employed to monitor the structure formation in concentrated, aqueous dispersions of model, electrostatically stabilized, polymer colloids. A regime of fractal scaling is observed in the vicinity or the gel point, as signified by a power law decay in the autocorrelation function(More)
