Question about Synthia

Dear all,

I would like to ask another question abour Synthia module.

When I calculate polymer properties by Synthia, there is no change despite increasing the molecular weigh of polymer.

For exmaple, molar volume of polymer having molecular weight of 1000 amu is wxactly same with the polymer having molecular weight of 10000 amu.

Could you all please give a comment on this?

Best regard,
