COMPOSITION FOR MANUFACTURING ORGANIC GLASS Russian patent published in 2005 - IPC

Abstract RU 2254343 C1

FIELD: polymer materials.

SUBSTANCE: invention relates to manufacturing sheet organic glass based on methyl methacrylate copolymers and used, in particular, in making glass parts of aircrafts. Starting composition comprises per 100 wt parts of methyl methacrylate/methacrylic acid monomer mixture with 0.05-3.0 wt parts methacrylic acid, following ingredients, wt parts: phenol-type antioxidant 0.01-1.0, organic hydroperoxide 0.05-3.0, substituted thiourea 0.03-1.0, and optionally UV stabilizer 0.1-2.0, and/or UV absorber 0.005-0.5, and/or multifunctional (meth)acrylic ester as crosslinking agent 0.1-15.

EFFECT: increased heat resistance of organic glass up to ability to resist for a short time (up to 1h) heating at temperatures up to 240°C without appearance of visible defects such as bubbles and cracks.
