Abstract—New fungicidal and antimicrobial siloxane oligomers were prepared on the basis of
γ-aminopropyltriethoxysilane and a series of bisphenols. Chemical immobilization of these oligomers on the surface
of various fabrics was studied with the aim to develop textile materials resistant to microbiological degradation.
The world’s demand for various bactericidal and
fungicidal additives to polymers considerably increased
recently, especially in medicine and in production of
materials contacting with foodstuffs .
Today an urgent problem is the development and use
of textile materials exhibiting antimicrobial (bactericid-

The purity of all the bisphenol compounds was
checked by TLC .
Carrier oligomers [penta-γ-(aminopropyl)heptaeth-
oxypentasiloxane and deca-γ-(aminopropyl)dodecaeth-
oxydecasiloxane] were prepared by hydrolytic polycon-
densation in dry ethanol .
Antimicrobial siloxane oligomers (ASOs) were
prepared in situ. For this purpose, to alcoholic solutions
of carrier oligomers we added appropriate amounts of
bisphenols (Table 1). The reaction mixture was reﬂ uxed
