CRYSTALLIZATION KINETICS OF ETHYLENE-PROPYLENE COPOLYMERS PREPARED BY LIVING COORDINATION POLYMERIZATION

Received Date: 13 March 2008
Revised Date: 5 May 2008

In this paper, crystallization kinetics of a series of ethylene-propylene copolymers prepared by living polymerization coordination catalyzed by a fluorinated bis(phenoxyimine) Ti catalyst (FI-EP copolymers) was studied, and was compared with that of ethylene-propylene copolymers prepared by a conventional Ziegler-Natta catalyst (ZN-EP copolymers). It is found that, the Avrami exponent and the crystallization rate constant of the FI-EP and ZN-EP copolymer show similar dependence on crystallization temperature, but the FI-EP copolymers exhibit a larger Avrami exponent than corresponding ZN-EP copolymers at high crystallization temperature and at low propylene content level. The crystallization temperature, equilibrium melting temperature and crystallinity of the FI-EP copolymers decrease more rapidly with propylene content than those of the ZN-EP copolymers. This can be attributed to their different comonomer distributions and partially to the different molecular weight distributions at low propylene content level.
