| Abstract: | Summary An unusually strong molecular weight dependence of the specific refractive index increment which has been reported for solutions of oligomers (M < 103) of p-2-methyl phenylene is attributed to the exaltation of polarizability of phenylene units. The saturation length is estimated to be l s≅ 6 phenylene units. Received: 3 November 1997/Revised version: 20 April 1998/Accepted: 22 April 1998 |
