Abstract: A method of preparing a polymer article comprising preparing a plurality of polymer samples having a lower molecular weight (LMW) component and a higher molecular weight (HMW) component; sieving each of the plurality polymer samples to produce a corresponding plurality of sieved polymer samples; determining a heterogeneity value for each of the plurality of polymer samples; identifying at least one polymer sample from the plurality of polymer samples having a predicted gel count of less than 100 gels/ft2 wherein the predicted gel count is a function of the heterogeneity value; and fabricating a film from the identified polymer sample having a predicted gel count of less than about 100 gels/ft2.
