화학재생 폴리에스터 칩의 물성향상 연구

초록

Chemically recycled/virgin poly(ethylene terephthalate) (PET) blends were prepared by melt blending toimprove the physical properties of the chemically recycled PET. The effect of virgin PET on the mechanical and thermalproperties, molecular weight, and crystallinity of the chemically recycled/virgin PET blends was investigated. The tensilestrength and modulus of the chemically recycled/virgin PET blends increased with increasing virgin PET content. Thecrystallinity of the chemically recycled/virgin PET blends depended significantly on the recycled PET content because ofthe nucleation effect of the residual catalyst generated from the depolymerization of PET. The color index of thechemically recycled/virgin PET blends was also investigated to determine the color of the blends numerically.
