Abstract

A model for predicting the molecular weight distributions of mechanochemically degraded star polymers has been developed. The model was shown to be in good agreement with experimental distributions and average total molecular weights obtained from ultrasonically degraded three-arm star poly(methyl acrylate)s. Generalization of the model to four- and n-arm star polymers was also achieved. The models are straightforward to use, and thus, all calculations were completed in Microsoft Excel.
