After the first polymerization at -20 degrees C, the same amounts of propylene were added at 25 degrees C for the second polymerization. The resulting PP was syndiotactic-rich (rr = 0.75), the value of which is the arithmetical average ((0.89 + 0.60)/2 = 0.745) of those produced at -20 and 25 degrees C.
