I think the only real option for this is a clear plastic sheet that's had a chemical resistant thin film applied to the faces. One commercially available example is Makrolon AR2, it's polycarbonate with some proprietary coating that's listed as having >24hrs resistance to acetone and a few other chemicals.

Alternatively, cast your own sheet (or straight your close-to-final piece) using a mold from a chemical resistant 2 part epoxy. Usually, difunctional or polyfunctional amine hardeners confer chemical/temperature resistance, causing a polymerization in a 3D cross-linked network (it also means saying goodbye to thermoplasticity).
Google search - customize it for the TLD/geo area you live in.
Example of a result that works for me (haven't use it yet, but I had a chat with a sale representative and confirmed that it maintains its clear/mechanical resistance when using with acetone after the cure).

@Shawn You are correct, getting optically clear or even just transparent PP 1/8" sheet isnt trivial. If semi-transparent white PP sheet isnt an option, then one should probably look further for less common proprietary plastics.More
From what I can tell, clear polypropylene is biaxially oriented polypropylene, it looks like it gets stretched in 2 directions while being formed. I think this process is mostly used for thinner packaging material, something a few mil thick. I wasnt able to find anything in sheet form thats an 1/8" or 1/4" thick.More
+1 iPP can be made to crystallise in structures smaller than optical wavelenght. Its done with comonomer contents and/or tacticity defects in a small percent range and/or a lot of nucleating agents.More

According to Palstics International's Chemical Resistance Chart, the A-rated plastics (no solvent attack) towards acetone are:
Among these, polypropylene appears to be the only plastic that satisfies all criteria.
