3 The specification defines "melt flow ratio" or MFR as (high load melt index)/(melt index) using a high
load of 21 kg versus a melt load of 2 kg (page 6). Bailey uses slightly different loads, i.e. a high load of 21.6 kg verus
a melt load of 2.16 kg (column 3, lines 26-29).
4 See Answer page 3, fn. 1.
5 According to Bailey, example 11 blend has an I of 5.0 and an I of 0.06 (Table XVI, column 22), which

would provide an I /I of 83.
