Abstract
The crystallization behavior of poly(ethylene terephthalate) (PET) /ethylenemethyl acrylate-glycidyl methacrylate copolymer (E-MeA-GMA) blend was studied. The extent of reaction and the reaction rate between PET and E-MeA-GMA were measured with torque rheometer, FT-IR and SEM. The effects of the grafting reaction on the crystallization behavior were investigated with DSC and time-resolved light scattering (TRLS) techniques. The morphological change at the lamellar level was also examined by using a small angle X-ray scattering (SAXS) method.

무정형 고분자인 ethylene-methyl acrylate-glycidyl methacrylate 공중합체 (E-MeAGMA)와 결정성 고분자인 poly(ethylene terephthalate) (PET)와의 블렌드에서 그라프트 반응에 따른 PET의 결정화 거동을 조사하였다. PET와 E-MeA-GMA간의 그라프트 반응 수준을 torque rheometer, FT-IR, SEM을 이용하여 확인하였으며, 반응시간에 따른 결정화 거동 변화를 DSC와 광산란 방법을 이용하여 관찰하였다. 또한 라멜라 수준의 결정구조를 소각 X선 산란법을 이용하여 조사하였다.
