Poly(butyl acrylate) (PBA) is a family of organic polymers with the formula (CH₂CHCO₂CH₂CH₂CH₂CH₃)_n. It is a synthetic acrylate polymer derived from butyl acrylate monomer. The polymers are colorless. This homopolymer is far less important than copolymers derived from methyl acrylate and other monomers. It has a low glass-transition temperature of about -43 °C (20 °C).^{[clarification needed]}
