摘要
The polyester poly(1,10-decanediol /1, 10-sebacate) (PSD) was synthesized by means of Novozyme 435 catalyzed condensation polymeriza- tion of 1,10-decanediol and 1,10-sebacic acid. Both hydroxyl chain ends of the resulting PSD were modi- fied by esterification with α-bromopropionyl bromide to obtain difunctional macroinitiator, which was sub- sequently used in the ATRP of S t using CuCl/2, 2′- bipyridine (bpy) as the catalyst system to afford the triblock copolymer, polystyrene-block-poly(1,10-dec- anediol/1,10-sebacate)-block-polystyrene (PS t-b-PSD- b-PSt). Molecular weight distribution and structure of the resulting triblock copolymer was confirmed by Waters 410 Gel permeation chromatography (GPC) and measurements of nuclear magnetic resonance (NMR) analysis.
The polyester poly（1,10-decanediol /1, 10-sebacate） （PSD） was synthesized by means of Novozyme 435 catalyzed condensation polymerization of 1,10-decanediol and 1,10-sebacic acid. Both hydroxyl chain ends of the resulting PSD were modified by esterification with α-bromopropionyl bromide to obtain difunctional macroinitiator, which was subsequently used in the ATRP of St using CuCI/2, 2＇- bipyridine （bpy） as the catalyst system to afford the triblock’ copolymer, polystyrene-block-poly（1,10-decanediol/1,10-sebacate）-block-polystyrene （PS t-b-PSD- b-PSt）.
