\rē-tär-dā-shәn, ri-\ n (1) To reduce the rate at which a polymer is formed. Retardation occurs as a result of a reaction between the chain-initiating species and the inhibitor or retarder. (2) The actual distance of one of the doubly refracted rays behind the other as they emerge from an anisotropic particle. It depends on the difference in the two refractive indices, n2 – n1, and the thickness.
