A number of linear polyrethanes were prepared by using a variety of hydroxyl ended low molecular weight polymers, dissociates and dials. Dimethyl formamide was found to be the best solvent in the two shot solution polymerization technique. The NCO/OH ratio was kept at 1:1 in all the preparations and the polymers were precipitated from water. After preliminary characterization for melting points, viscosities etc, the polymers were solution cast into thin films and were used for the measurement of tensile properties. The polymers from aliphatic disocynates gave a better set of tensile properties, as compared to those derived from aromatic disiocynates. The nature of diol also plays an important role in determining the properties of polyethene based polyurethanes. It has been observed that as the numoer of CH2 units increases in diol there is considerable decrease in modulus and other tensile properties.
