Effect of POE Grafting Degree and Compatibilization on the Properties of PBT/POE Blends

Article Preview

Abstract:

Poly (ethylene 1-octene) (POE) was functionalized to varying degrees with maleic anhydride (MA) by melt grafting processes. Fourier transform infrared spectra (FT-IR) confirmed that maleic anhydride was successfully grafted onto the POE. The POE-g-MAH elastomers were used to toughen Polybutylene terephthalate(PBT). The mechanical properties, morphology and the dispersal phase size were investigated. Results showed that the grafting degree strongly influenced the morphology, mechanical properties and the dispersal phase size. All results in this paper were consistent, and showed good interaction between POE and PBT, which was proven by the mechanical properties of blends.
