Process for producing polymethylmethacrylate molding materials with a neutral color
Products based on polymethylmethacrylate (PMMA) so resistant to yellowing and so highly transparent that even the edges of plates produced from this material have a neutral colour, i.e. do not display any yellow tone. This effect is obtained by the admixture of 5 to 50 ppm inorganic, reducing phosphorus compounds after polymerisation. This enables the brightener content to be reduced under 10 ppb, and so the end product may also be used in contact with foodstuffs.
