FIELD: chemistry.
SUBSTANCE: composition for obtaining plexiglass contains 100 pts.wt. methacrylic monomer 0.0002-1 pts.wt. polymerisation initiator, 0.005-0.5 pts.wt. UV absorbers and 2.0-7.0 pts.wt. biphenylmethacrylate. The composition may also contain 0.05-10.0 pts.wt. of a linking agent. Sheets of plexiglass derived from the proposed composition are applicable for glazing parts for aircrafts.
EFFECT: increasing the stability of sheet plexiglass to the action of UV-irradiation while preserving its heat resistance.
