## Abstract Fourierβtransform infrared (FTIR) spectroscopy has been used to investigate the segmental orientation of poly(vinyl chloride) (PVC)/poly (Ξ±βmethylβΞ±β__n__βpropylβΞ²βpropiolactone) (PMPPL) blends in uniaxially stretched samples over a wide range of compositions and draw ratios. The result
The Fourier transform infrared (FTIR) spectroscopic studies of the poly-(styrene-co-acrylonitrile) (SAN) and poly(vinyl chloride-co-vinyl acetate) (VYHH) blends produced by different blending techniques, viz., solution blending, melt-blending, and also the co-precipitation methods of blending, were
## Synopsis The Young's moduli of samples of poly(viny1 chloride) containing either no plasticizer or 5 pph of dioctyl sebacate were drawn uniaxially at 80Β°C to draw ratios, A, in the range 1-3.3. The moduli, determined by a three-point bending method were found to increase monotonically with X to
