Abstract

Oligoether carbonates R (PO) n OCO2 (PO) n R, where R= Me, Et, or H, PO= propylene oxide ring-opened unit, and n= 1, 2, 3, 4,~ 10, and~ 30, have been prepared and characterized by ESI/MS or MALDI/MS and 13C {1H} NMR spectroscopy in addition to 1H NMR, DEPT, COSY, and HMQC. The propylene oxide (PO) units have been derived from S- PO and rac-PO. The compounds have been examined as potential models for polyether ...
