Poly(methyl acrylate) - Wikipedia

Poly(methyl acrylate) (PMA) is a hydrophobic synthetic acrylate polymer.PMA, though softer than polymethyl methacrylate (PMMA), is tough, leathery, and flexible.. It has a low glass-transition temperature about 10°C (12.5°C in case of PMA 38).. High-energy radiation leads to cross linking in PMA. However in polymethyl methacrylate (PMMA), a compound similar to PMA, degradation occurs …
