HCID 62697Benzene, ethenyl-, polymer with 1,3-butadiene

Procedure

The refractive indices of butadiene, styrene, acrylonitrile and methyl methacrylate homo-polymers are 1.515, 1.591, 1.515 and 1.491 respectively. A butadiene/styrene ratio of 85:15 gives a calculated refractive index of (0.85×1.515)+(0.15×1.591)=˜1.526.
