Hyper-Dispersant Modifier Prepared and Applied in Polyethylene Composites

Abstract:

A new hyper-dispersant with Silicon radicals as anchoring group and poly (butyl acrylate) as solvatable chain was synthesized and its effect on the properties of PE/Talc composites was investigated in this paper. Fourier transmission infrared spectroscopy (FT-IR) results show that the modifier react on the Talc powders surface and the modified Talc powders particles. The impact strength of PE/Talc composites increased about 32.5% compared with that of PE/Talc (filled with same non-modified fraction) respectively. Based on surface analysis by scanning electron microscope (SEM), the Talc powders particles buried well in PE matrix when Talc powders was coated with the new modifier.
