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 PMA38). High-energy radiation leads to cross linking in PMA. However in polymethyl methacrylate (PMMA), a compound similar to PMA, degradation occurs instead. It is soluble in dimethyl sulfoxide (DMSO).PMA is water-sensitive and unlike PMMA, is not stable against alkalies. It is used as macroinitiator to initiate the copolymerisation of HEMA and DMAEMA.Also used in leather finishing and textiles. Derivatives of this polymer are commonly used in orally administerd pharmaceutical formulations to target specific regions of the gastrointestinal tract.
