COMPOUND FOR PRODUCTION OF ORGANIC GLASS Russian patent published in 2006 - IPC C08F220/18 C08F220/06 

FIELD: production of sheet organic glass on base of copolymers of methyl methacrylate by method of polymerization in block.

SUBSTANCE: proposed compound contains the following components, parts by mass: methyl methacrylate, 60-70; methacrylic acid, 10-20; 4-chloro-phenyl methacrylate or 2-,4-,6-trichloro-phenyl methacrylate or 2,3, 4, 5,6 pentachlorophenyl methacrylate, 15-25 and polymerization initiating agent, 0.0002-1.0 per 100 parts by mass of monomer mixture. Compound may additionally contain the following components per 100 parts by mass of monomer mixture, parts by mass: UV stabilizer, 0.01-2.0; UV absorber, 0.005-0.5; and cross-linking agent or their mixture, 0.05-10. Glass produced by proposed method is adaptable for glazing of aircraft and helicopters; it may be also used as structural material in shipbuilding, mechanical engineering, instrumentation engineering and other industries.

EFFECT: reduced water absorption; enhanced strength of sheet glass.
