Abstract
SummaryLiving polymerization of hexaethylcyclotrisiloxane was achieved with nBuLi-(nBuO)3PO at room temperature to produce living poly(diethylsiloxane). The molecular weight of the polymer increased in direct proportion to monomer conversion and to the reciprocal to the initial nBuLi concentration. Molecular weight distribution remained 1.1–1.2 during the polymerization. The polymerization was completed only after 1 day despite no solvent was used. When a compound containing SiOH groups was added to the polymerization system, the number of polymer chain agreed with a sum of nBuLi and SiOH groups.
