In this paper the reaction kinetics of ring-opening polymerization of propylene oxide (PO) by using a catalyst of tetraphenylporphyring AlCl complex (TPPAlCl) has been studied by NMR at various temperatures
which includes reaction order
reaction rate constants
activation energy
number of active center
average length of polymer chains and polymer tac-ticity.The NMR method
which is simple and rapid
gives a wealth of real information. It can be applied to qualitative or quantitative analysis and is one of modern measuring methods in kinetic researcn.
