Note：


1. M1 in the table is the median value of intrinsic viscosity.  in general M1=0.680 or it should be determined by both buyer and seller.

2. M2 in the table is the median value of melting point.  M2 can be chosen between 90℃-220℃ or it should be determined by both buyer and seller.

3. M3 in the table is the median value of color b. in general M3=2 or it should be determined by both buyer and seller.

4. DIethylene glycol needs to be agreed by both buyer and seller.
