<p> This dissertation describes an investigation into the free radical polymerization of styrene in continuous stirred tank reactors (CSTR's). The aim was to develop a steady state polymerization model which would accurately predict conversion and molecular weight distribution (MWD) up to high conversion. </p> <p> The dissertation is divided into three self-contained parts. Part I describes the testing and development of polymerization kinetics using a single CSTR. The single CSTR model is described. Theoretical and experimental
conversions and MWD's are compared and discussed. </p> <p> Part II describes the development of a model for a system of CSTR's. It is based upon the single CSTR model and the kinetics developed in Part I. Theoretical and experimental results for a three reactor system are compared and discussed. </p> <p> Part III describes the development of gel permeation chromatography (GPC) for measuring MWD. Molecular weight and resolution calibration data are presented and discussed. Four methods of chromatogram interpretation that correct for imperfect resolution are compared. </p> / Thesis / Doctor of Philosophy (PhD)
