Their loss causes premature brittleness, that shortens the useful life-span of the material. The oily surface of the PVC moldings as well as the

Since PMA is rather soft (T. = 6°C) it had to be copolymerized with ethylmethacrylate (T. = 75°C) (Salkind ., 1959). However, the main obstacle to commercialization was the high cost of acrylic monomers.
