Thermal and Mechanical Property Research of Polyethylene Modified by Reactive Quatemary Ammonium Salt

Abstract

In this investigation, dodecyl dimethyl(vinylbenzyl)ammonium chloride is applied to modify properties of polyethylene, and it is greatly focused on influences of it on the thermal properties and mechanical properties of this polymer. The results demonstrate that addition of this compound into polyethylene has little effect on thermal properties except for little improvement of its glass temperature, although it has reactive double bond in its molecular. Moreover, it is observed that it can enhance mechanical properties of this polymer and its addition has little change in colors of bulk materials. Therefore, it is believed that these excellent properties help to drive this antibacterial compound in applications.
