In this study, the polymerization kinetics of an uncatalyzed polyester based thermoplastic polyurethane formulation was characterized with Raman spectroscopy. Measuring the normalized scattering intensity of a band originating from the TPU diisocyanate, conversion was calculated as a function of tim

The emulsion polymerization of vinyl acetate was studied a t 50Β°C. It was found that the rate of polymerization was proportional to the 0.5 power of the initiator concentration and the 0.25 power of the number of particles. The number of particles was proportional to the power 0.5 f 0.05 of the emul
## Abstract Analysis of various timeβconversion curves obtained with different AIBNβconcentrations at 65Β°C led to relative rate constants of conversion in the liquid and precipitated phase. Due to the density difference between the two phases, the timeβ and conversionβdependent volume concentration
