Polymer crystallization and properties

Kinetic and thermodynamic processes: free-radical polymerization reactions initiation propagation bimolecular termination chain transfer rates in copolymerizations cross-linking reactions the locus of polymerization in emulsion systems the rate of an emulsion polymerization the three intervals of emulsion polymerization ab initio and seeded systems for mechanistic studies monomer concentration in latex particles phase-transfer events in emulsion polymerizations inhomogeneities in latex particles scope and methods for mechanistic investigation. Theory of the kinetics of particle growth: overview the simple zero-one system general description of zero-one systems the Smith-Ewart equation chain-length-dependent kinetics - the pseudo-Bulk equation chain-length-dependent compartmentalized systems summary and roadmap for modelling particle growth conclusions. Rate kinetics of particle growth - applications and mechanistic conclusions: rate coefficients and mechanism for entry rate coefficients and mechanisms for exit termination conclusions. Particle size distributions: introduction measurement of PSDs the evolution equations for the PSD solutions of the PSD evolution equations obtaining kinetic data from the PSD conclusions. Molecular weight distributions: the importance of molecular weight in polymer systems definitions of molecular weight distributions and averages rate parameters determining MWD modelling the MWD sample calculation of MWDs experimental measurement of MWDs some experimental results conclusions. Particle formation: introduction particle formation below the CMC particle formation above the CMC some important influences on nucleation conclusions.
