polypropylene; oxygen permeability; cooling rate
The influence of different cooling rates on the morphology and oxygen permeability of polypropylene containing ferrocene has been investigated. The spherulitic crystalline size and structure, which can affect the oxygen permeability are dependent upon the heating temperature, annealing time and cooling rate. The modulus of the composite was measured by dynamic mechanical analysis.
