Solubility parameter values for polypropylene as reported in the literature cover a rather broad span, ranging from 7.9 to 9.4 (cal./cm. 3 ) 1/2 . This communication suggests the approximate value 8.2. This value is based on the swelling and dissolution characteristics of polypropylene films in various organic liquids. A calculated value of 8.1, obtained by Small's method, compares well with the experimentally determined value.
