폴리부틸레 테레프탈레이트 합성에 관한 연구
A Study on Preparation of Polybutylene Terephthalate
초록
In the process that uses terephthalic acid(TPA) and 1,4-butandio(BD) for the production of polybutylene terephthalate(PBT), the influences of reaction conditions on % reaction, Xn(the degree of polymerization of oligo-PBT), and %BDlongrightarrowTHF(tetrahydrofuran) were investigated. With increasing mole ratio of BD:TPA, %BDlongrightarrowTHF increased and Xn decreased, but with increasing tetrabutyltitanate(TBT) concentration, %BDlongrightarrowTHF decreased and Xn increased. %BDlongrightarrowTHF increased greatly with increasing the reaction temperature in the rang of temperature between 21
