| Abstract: | The effects of varying amounts of organically modified nanoclay (NC), calcium stearate (Ca.St.), stearic acid (St.Ac.), and an impact modifier (IM) on the fusion characteristics of a rigid Poly(vinyl chloride) (PVC) nanocompound were investigated by using the L9 orthogonal method of experimental design. The materials showed varying effects on the fusion parameters. Thus, while the fusion time was lowered and the fusion factor increased by NC, Ca.St., and IM, the reverse was true with St.Ac. Effects on the minimum and maximum viscosities of formulations also varied with material type. The behavior of the materials is discussed in terms of their effects on the transformation of PVC grains. Thermal stability and color change were sensitive to NC content. J. VINYL ADDIT.
