摘要: Abstract Crystallization behavior and solid-state microstructure of poly(hexamethylene succinate) (PHS) its phosphorus-containing copolyesters with bulky pendent group (DDP) have been investigated. The molecular weight, chemical structure composition the were characterized confirmed by GPC, 1H 31P NMR. WAXD results suggest that DDP comonomer units in are noncrystallizable extruded from crystal lattice PHS. POM observations indicate spherulitic morphology becomes irregular blurry an increase content. kinetics analysis isothermal crystallization shows is retarded presence units. observed melting temperatures progressively depressed DDP. SAXS quantitative provides a proof significant long period mainly arises amorphous layer, because thickness lamellar increases slightly. A model copolyester proposed for depression equilibrium temperature.
