And there's the problem. Polyacrylonitrile is used to make fabrics. Acrylic is polymethyl methacrylate. Maybe you're talking about a co-polymer like polyacrylonitrile-butadine-styrene (abs plastic). Acrylic and ABS are two entirely different materials with noticeably different properties."The sign must be made of polyacrylonitrile" and I am like ok so you want Acrylic. Got it.
The reason they have to be so ridiculously precise in their specs is to make sure they are getting exactly what they're looking for and not someones substitutions. I routinely bid state contract jobs that take a $400 sign and make it $800 because they specify materials that aren't commonly available anymore.
