Thermal stabilization of poly(3-hydroxybutyrate) by poly(glycidyl methacrylate)

Autor: Moon Yeon Lee, Seung No Lee, Won Ho Park

Publikováno v: Journal of Applied Polymer Science. 83:2945-2952

Poly(3-hydroxybutyrate) (PHB)/poly(glycidyl methacrylate) (PGMA) blends with the PGMA content up to 30 wt % were prepared by a solution-precipitation procedure. The thermal decomposition of PHB/PGMA blends was studied by thermogravimetric analysis (T

Effect of Side Chains on the Thermal Degradation of Poly(3-hydroxyalkanoates)

Autor: Taek Seung Lee, Moon Yeon Lee, Won Ho Park

Publikováno v: Macromolecular Chemistry and Physics. 202:1257-1261

The PHAs with different pendant units such as methyl, vinyl, epoxide and hydroxyl groups at the terminus were prepared by biosynthesis or chemical modifications following the biosynthesis. The thermal decomposition behavior of these PHAs have been st

Preparation of bacterial copolyesters with improved hydrophilicity by carboxylation

Autor: Moon Yeon Lee, Won Ho Park

Publikováno v: Macromolecular Chemistry and Physics. 201:2771-2774

Poly(3-hydroxyalkanoate)s PHAs, containing pendant carboxyl groups were prepared by the chemical modification of unsaturated PHAs using potassium permanganate (KMnO 4 ) at 55°C, although there is a severe loss in molecular weight of PHAs during the

Epoxidation of bacterial polyesters with unsaturated side chains V. Effect of crosslinking on thermal degradation of epoxidized polymers

Autor: Won Ho Park, Moon Yeon Lee

Publikováno v: Polymer Degradation and Stability. 65:137-142

The epoxidized bacterial copolyesters, poly(3-hydroxyoctanoate- co -3-hydroxyl0,11-epoxyundecanoate)s (PHOEs), were crosslinked with succinic anhydride in the presence of catalyst or with hexamethylene diamine without catalyst at 90°C for 0.5–6 h.
