I need to cut a few inches from this PVC chair mat (if this isn't PVC, can you tell me what material it is). How do I achieve this?
I though of using an acrylic knife; will it work? The line will be straight and 40 inches long.

I see no reason why you should cut threads on a PVC pipe. It seems to me that this would be unnecessarily difficult and would weaken the pipe.
You should, instead, get a slip to thread adapter and glue it onto the pipe to thread it wherever you like. Any big-box hardware store or irrigation department should be able to provide this adapter.
Edit: Here is a link to such an adapter for $1.56at big orange hardware store. :
It sounds like you're using a crappy copper pipe cutter. To cut PVC, you want one of these instead:
I've used mine to cut thousands of PVC pipes and it does the job quickly and easily. You can probably find one for less than $10 and it will serve you well for life.

I've cut chair mats by laying them on a flat work surface. Then secure a metal straight edge along the cut line. (In my case I clamped a long piece of aluminum bar stock in place to the work surface with the mat in between).
A utility knife with a sharp blade was then used to score a cut line along the straight edge. Chair mats are a relatively soft plastic and it was not possible to use a score and break off type process. Instead I cut in the same place along the straight edge 3 or 4 times. I then removed the straight edge and clamps and positioned the cut line along the edge of the work surface. This allowed cut area to be opened slightly as the part to be removed was bent down over the edge of the work surface. Once the cut line was opened like this continued passes of the utility knife blade in the cut groove allowed the cut to be made deeper and deeper and eventually finish the cut.
