Cross-linked poly(orthocarbonate)s as organic solvent sorbents

A simple method for the synthesis of a series of cross-linked poly(orthocarbonate)s (CPOC), based on tetraethyl orthocarbonate, is reported. Structural evidence for CPOCs was obtained from C-13 solid-state NMR, FT-IR, and thermal analysis. All polymers have high and fast uptake of organic fluids such as tetrahydrofuran, dichloromethane, dichloroethane, and the dry-cleaning fluid blend trichlor.
