Description

General description

γ-Thiobutyrolactone undergoes copolymerization with glycidyl phenyl ether to form poly(ester-alt-sulfide).

Application

γ-Thiobutyrolactone was used to terminate the ring opening polymerization of ω-pentadecalactone to synthesize difunctional polyesters. γ-Thiobutyrolactone was used to study the mechanism of metabolism of sulphur containing heterocyclic compounds by lignin-degrading basidiomycete Coriolus versicolor.
