Is there a specific need to make PC crack ? or Are you getting the situation with any particular solvent ? This detail will help us to explore further.
Common solvents that can dissolve polycarbonate include dichloromethane, chloroform, and certain types of ketones like acetone. It is important to use these solvents in a well-ventilated area and with proper safety precautions due to their potential health risks.

Crack
I looked up the price for a 1" x 12" x 12" piece of both polycarbonate and polyacrylate, and the polyacrylate was significantly cheaper. There were several different types of polycarbonate you could buy in this size, ranging in price between $100 and $300. There was only one kind of acrylic available in the size I specified (cast acrylic) and it was about $50. If instead I chose a 1/2" x 12" x 12" the prices were closer, but the polycarbonate was still more expensive on average. There were even more types of polycarbonate in this size available, ranging from $25 to $155. There were also several types of acrylic in this size, from $15 to $40. NOTE: Prices are from the McMaster-Carr website-- see Web Links to the left of this answer. They have many many shapes and sizes for additional price comparisons if necessary!
Crack is a powder, or a rock. You smoke it to feel a high. Not sure what kind of high, I personally have not smoked it.
with some kind of an acid based solvent
But crack
crack cocain
That would be a basement crack; legal but very expensive. A bicuspid crack is legal but be very painful. A bumper crack is legal but also expensive unless you're well insured.
The solvent, usually water.
firstly it is solvent and that means it can harm you and it is a kind of acid!
The solvent evaporates and leaves behind the pigment behind.
