Is there a well-established reference table of porosity (free volume) of commonly used polymers?

Thanks in advance.

Also dimensions of said (nano)pores. Thanks again.

There is a nice paper about porosity in polymers:

Correlation Between Fractional Free Volume and Diffusivity of Gas Molecules in Glassy Polymers

Here is the citation in part:
Journal of Polymer Science Pt. B vol. 37, p. 3344 (1999)

It is nice because it has a table with a lot of polymers which includes the inverse free volume fraction. The free volume always exceeds 11%. It's like polymers are at least 11% nothing.
