Do you disagree that where a solvent causes an amorphous polymer to
craze, this is because the polymer is principally soluble in it?

This is environmental stress cracking. It's not the polymer being soluble
in the solvent. If anything, it could be regarded as the solvent going
into solid solution in the polymer, changing its fracture behaviour.

It's not a coincidence that a film of ethanol on acrylic creates cracks

Bull**** it does.

and water and other liquids don't.

I'm going to leave it to you to google *acrylic soluble in ethanol* or
*acrylic soluble in alcohol* and check if the consensus is that acrylic is
partially soluble in ethanol.

Science isnt about consensus, its easy to check that silly claim.

I did search for *acrylic "solid solution"* but didn't find any meaningful
hits. Perhaps you can assist?
