"Plexiglas" is a Rohm and Haas Trademark for acrylic.  The "official"
chemical name for acrylic is Poly(methyl methacrylate) [PMMA].

More info can be found at:
 http://www.psrc.usm.edu/macrog/pmma.htm

Other tradenames for acrylic include "Lucite" (DuPont).

WARNING:  If PMMA burns, free radical cyanide (gas chamber)
is produced!!!  Do not burn PMMA, and do not use where combustion
or ignition temperatures may be approached!   This is one reason why
people succomb to smoke inhalation in house fires, burning acrylics produce
deadly smoke and free radical compounds!  Epoxy, polyethylene
(UHMW), even ceramics may be a better insulator then Plexiglas in
high temperature applications in high voltage appartus.
