Part of the book: Oligomerization of Chemical and Biological Compounds
The effect of ethylene oxide (EO) heterogeneous heterobifunctional acyclic oligomers (HEHAO) on wetting represents a continuation of the review of the research partly published by the author on ethylene oxide (EO) homogeneous heterobifunctional acyclic oligomers (HOHAO). Heterogeneous polyoxyethylene chains obtained by the anionic polymerization of EO (“anionic ring-opening polymerization”) with a certain polydispersity degree are hydrophilic, flexible (specific spatial conformation), biocompatible “bridges,” without toxicity. After the purification of polyethoxylated higher alcohols (technical products), heteroderivatization performed by an adapted classical reaction scheme led to the colloidally evaluated HEHAO series.
