Öğe Nature-derived renewable polymers to replace commodity plastics(Amer Chemical Soc, 2018) Nsengiyumva, Olivier; Sahmetlioglu, Ertugrul; Ha Thi Hoang Nguyen; Gokturk, Ersen; Miller, Stephen[Abstract Not Available]Öğe Silicon Acetal Metathesis Polymerization(Amer Chemical Soc, 2016) Sahmetlioglu, Ertugrul; Ha Thi Hoang Nguyen; Nsengiyumva, Olivier; Gokturk, Ersen; Miller, Stephen A.A kinetic study revealed that the acid-catalyzed (p-TSA) equilibration of Me2Si(OMe)(2) and Me2Si(OEt)(2), forming Me2Si(OEt)OMe, is established in 300 min in benzene at room temperature. This silicon acetal metathesis reaction is exploited for the step-growth polymerization of bissilicon acetals (MeOSiMe2OROSiMe2OMe) with metathetical loss of Me2Si(OMe)(2). Thus, a convenient and generalized silicon acetal metathesis polymerization (SAMP) method is introduced as the acid-catalyzed copolymerization of a diol (HOROH) and Me2Si(OMe)(2), driven by elimination of methanol and/or Me2Si(OMe)(2). SAMP constitutes an effective and powerful strategy for manipulating the most common bond in the Earth's crust, the silicon oxygen bond.Öğe Sustainable polysiloxanes via siloxane metathesis(Amer Chemical Soc, 2015) Sahmetlioglu, Ertugrul; Gokturk, Ersen; Nsengiyumva, Olivier; Miller, Stephen[Abstract Not Available]
