Chemical properties
Colorless to light yellow liqui
The Uses of (S)-Styrene oxide
(S)-(-)-Styrene oxide can undergo copolymerization with CO2 to form the corresponding polycarbonate in the presence of a cobalt-based catalyst system.
Definition
ChEBI: The (S)-enantiomer of styrene oxide.
General Description
Styrene oxide is an oxirane derivative, which is used as a monomer for the synthesis of polyesters with relatively high?Tg values via ring-opening copolymerization. It can also be used as a useful intermediate in the preparation of levamisole, a nematocide?and anticancer agent.
