Homogeneous Ziegler-Natta polymerisation: A kinetic approach .2. Transient-state kinetics [PDF]

, 1997
An integrated view is presented of several possible mechanisms applicable to the interpretation of homogeneous Ziegler-Natta polymerisation. In this paper, the transient aspects related to the kinetics of Ziegler-Natta polymerisation are investigated ...
