Evaluation of Structures and Morphologies of Recycled PC/PET Blends Fabricated by High-Shear Kneading Processing
We fabricated polymer blends of recycled-PC (PC) and recycled-PET (PET) using high-shear processing technology. We also assessed its structure, morphology, and physical properties. Results of DSC measurements show that T-g of PC and T-c of PET shifted to higher temperatures by kneading under high-shear conditions. Results show further that the T-m of PET shifted to a lower temperature. Moreover, compatibilization progressed. TEM observations show that the PET domain was not confirmed completely under the kneading condition of 1000 min(-1)/10 s or more. Compatibilization progressed. Tensile test results show that the PET ratio of 30 wt% (1000 min(-1)/10 s) has higher breaking strain than neat PC does. Chemical resistance test results obtained by good solvent of PC demonstrated that blending of PET makes PC elution difficult.
