Poly(methyl acrylate) (PMA) is a family of organic polymers with the formula (CH2CHCO2CH3)n. It is a synthetic acrylate polymer derived from methyl acrylate monomer. The polymers are colorless. This homopolymer is far less important than copolymers derived from methyl acrylate and other monomers. PMA is softer than polymethyl methacrylate (PMMA),[1] It is tough, leathery, and flexible.[2]
