Polyether-polyester block copolymers with potassium titanyl oxalate and titanium dioxide as catalyst systems have been studied. It was found that there was a simple relationship between melt index and intrinsic viscosities of the copolymers obtained from different catalyst systems
but such relationship varies with different catalysts. A simple calculation equation for intrinsic viscosity has been derived.
