Characterization of polyethyleneimine modified with organotin halides. Thermal, solubility, and fungal properties

摘要

AbstractModified polyethyleneimine products are hydrophobic with products from monohalotin reactants soluble in HMPA, DMSO, CHCI3and 2,4‐pentanedione, while products from dihalotin reactants are insoluble in all solvents. Antifungal activity varies markedly with the nature of the tin moiety. For products from triphenyltin chloride, antifungal activity is widespread and suitable to about 40 ppb of the polymer, which is clearly acceptable for medical and industrial uses. Thus, such modified polymers can be used as retarders of fungi related rot and mildew. The products show moderate high‐temperature stabilit
