Kinetics of Shear Induced Crystallization

Part of the NATO ASI Series book series (NSSE, volume 302)


In this lecture it will be shown how it was accomplished to unravel the kinetics of shear induced crystallization of i-PP by a series of novel experiments. In this connection the method of short-term shearing gained a central position. It enabled a practical separation of the period, in which precursors were formed under influence of shear, from the later period of lateral lamellar growth. The findings of the latter period permitted safe conclusions with respect to the processes occurring in the shear period. The influences of molar mass distributions and a nucleation agent are discussed.
