An infrared method has been developed for the determination of the isotacticity of polypropylene in the 90-100~o range. The method requires the annealing of thin films a t 165-167Β°C. for 3 hr. in an inert at>mosphere, followed by slow cooling to room temperature. For approximate answers the ratio of
