Biogenic polyamines are long linear chains composed of 3 or more amino groups interconnected by methylene bridges (CH2)n where n typically is 3-5. Spermine is a quintessential example, isolated as its crystalline phosphate salt from human sperm by Anton van Leeuwenhoek in 1678. Spermine, and its bio-genetic precursor spermidine, occur in almost all tissues and they play a major role in the modulation of calcium-dependent immune processes and in cell differentiation and proliferation. The discovery that polyamines are structural components of potent spider neurotoxins has lent a certain frisson to their synthesis and it has elevated one of the dullest groups of natural compounds an aura of interest. 

The caticHiic surfactants are used infrequently in emulsion polymerization t pli-cations since they are not compatible with the anionic surfactants and with the (typically) negatively charged latex particles. These surfactants are usually of the following types salts of long chain amines, polyamines and their salts, quaternary ammonium salts (e.g., hexadecyltrimethyl ammonium bromide), polyoxyethyle-nated long-chain amines and their quatemized doivatives, and amine oxides [89].
