WebSep 12, 2024 · In polymer chemistry, the width of the distribution of molecular weights is described by the dispersity (Ð, also called, in older texts, the polydispersity or the polydispersity index, PDI). The dispersity of a polymer sample if often between 1 and 2 (although it can be even higher than 2). The closer it is to 1, the narrower the distribution. WebJun 13, 2024 · [0002] Schiff bases are unique compounds having a C═N functional group, sometimes this bond referred to as an azomethine bond and possess the general formula R1 R2 C═NR3 (R3 not equal to H). Schiff bases are produced by condensing primary amines and carbonyl compounds (aldehyde & ketones).
