| Viscoelasticity and Morphology of Soft Polycarbonate as a Substitute for Poly(vinyl chloride) (FUNDAMENTAL MATERIAL PROPERTIES-Molecular Rheology) (2001) | |||||||||||||
Abstract | |||||||||||||
| The soft polycarbonate resins, SPC, were newly developed as a substitute for soft poly(vinyl chloride). The soft polycarbonates are multiblock copolymers composed of bisphenol A polycarbonate, PC, and polydimethylsiloxane, PDMS. SPC resins are clear, transparent, and tough. Viscoelasticity and morphology of the resins were investigated to control physical properties of the resin. Electron microscope and small angle X-ray scattering experiments revealed that the SPC formed microdomain structures. Rheological measurements were used to discuss continuity of PC-rich phase domain, which determined the modulus around the room temperature. | |||||||||||||
