General description
Dimethyl terephthalate undergoes enzymatic polycondensation with 1,8-diaminooctane to yield oligo(octamethylene terephthalamide).
Application
Dimethyl terephthalate was used to synthesize silicone aromatic polyesters by the transesterification reaction with α,ω-bis(hydroxyalkyl)-terminated poly(dimethylsiloxane) in toluene. It was used in the synthesis of multiblock copolymers consisting of polyiso-butylene, dimethyl terephthalate and 1,4-butanediol.
