Summary

Surfactants of the formula [(CH3)3SiO]2CH3Si(CH2)3(OCH2H2)nOCH3, n = 3 to 9, have been synthesized. The temperature and concentration dependent spreading performance on hydrophobized Si-wafer surfaces has been investigated. Pronounced spreading velocity maxima were found at 6°C (n = 4), 26°C (n = 6) and 40°C (n = 8). A single superspreading component does not exist. The ability to spread is closely related to the phase transition temperature for La (lamellar phase) —+ 2 (two-phase system).
