Synthesis of terpene–poly(ethylene oxide)s by t-BuP₄-promoted anionic ring-opening polymerization

Grignard-based anionic ring-opening polymerization of propylene oxide activated by triisobutylaluminum

“…Bulky and strong organic bases, called aminophosphazenes, were used as deprotonating agents of alcohols to obtain higher polymerization rates of epoxides [19][20][21]. t-BuP 4 was the most used base for this purpose [22][23][24][25][26][27]. Polymerization systems based on monomer activation developed first by Inoue on propylene oxide were shown to strongly increase the polymerization rates [28,29].…”

Novel polymeric derivatives of betulin with anticancer activity

“…In literature, however, there are only several reports describing the fabrication of polymeric forms of betulin, including polyesters, polyurethanes and polyethylene oxide conjugates. [9][10][11][12] These materials exhibit high porosity and are used mainly in non-biological applications, e.g. for gas adsorption studies.…”
