AN INVESTIGATION OF THE FLAMMABILITY, MORPHOLOGY AND TORQUE RHEOLOGY OF POLY(VINYL CHLORIDE) WITH SILANES AND CU'2+ MODIFIED MONTMORILLONITES

摘要

Sodium montmorillonites were treated with silane coupling agents and copper(II) sulphate and PVC composites fabricated therefrom in a twin-screw extruder. The microstructures of the modified montmorillonites and composites were characterised by X-ray diffraction and scanning electron microscopy and the flammability, morphology, rheology and mechanical properties of the composites investigated by various techniques, including the cone calorimeter method, TGA, torque rheometry and tensile, flexural and impact testing. 29 refs.
