The compatibility of poly(vinyl chloride–vinyl acetate) copolymer (P(VC‐VA)) with thermoplastic polyurethane elastomers (TPU) was studied using Fourier transform infrared spectroscopy, optical microscopy and solubility parameters. The Gibbs free energy of mixing for the polymer–solvent system was calculated. The mechanical studies show that decrease in the P(VC‐VA)/TPU ratio decreases the tensile strength. © 1997 SCI
