The amount of polypropylene (PP) extracted by hot solvent extraction increased with increasing naphtha in a naphtha/reformate solvent blend. The stress-strain curves formed the basis for the calculation of several mechanical properties of the residual film. The yield stress, the natural draw ratio,
Three-component composites consisting of polypropylene (PP) matrix, poly-(vinyl butyral) (PVB) modifier, and mica filler at various ratios of matrix to modifies and a constant mica content (30 wt %) were prepared by using two different kinds of PVB, viz., PVB and PVB-P. By correlating with the morph
