1. What means environmental friendliness? Please explain the environmentally-friendliness of microcellular PP materials.
2. Please give the parameters of OBC, including but not limited to molecular weight, composition, melting point, soft point, and so on.
3. Please explain the reason for adding PP-G-MAH to the matrix.
4. Please give the diagram of the extruder to show the inlet for critical supercritical N2.
5. P5, Equation (5). Why not consider PP-G-MA when calculating the crystallinity?
6. Please give DSC curves of pure PP-G-MA and pure OBC in Figure 3 for comparison.
7. The matrix of the blends is pure PP with 5wt% PP-G-MAH, however, PP, pure PP and the first sample were not clearly defined in the text, and they are very confused!
8. In order to interpret the rheological behavior of the blends, the curve of pure OBC must be added in Figure 5.
9. Check the caption for Figure 6! a-b or a-d?
