Does anybody know where I can find diffusion coefficients for Arkopal or Igepal (or other types of surfactants) into polyethylene PE?

I am investigation environmental stress cracking and I try to shed some light on how surfactants accelerate crack growth in polyethylene PE. As a result I have some further questions:

If stress is applied to polyethylene PE, will the rate of Diffusion increase?

Is the rate of diffusion in orientated polyethylene PE smaller than in isotropic polyethylene PE?

What is the influence of the crystalline / amorphous fraction in the Polyethyelene?

Any help would be appreciated!
Regards
Markus
