| Description |
The specific refractive index increments (v) of polybutadiene (PB)
at 5460 and 4360 Awavelengths and of styrene-butadiene rubber at
4360 Awavelength were determined in various solvents, whereas
the values of v for crepe rubber at 5460 and 4360 Aand for polystyrene,
polymethyl methacrylate, and styrene-methyl methacrylate
at 5460 Awavelength were taken from the literature. From these
values mathematical equations are proposed whereby the refractive
index of these polymers can be determined from the refractive index
of solvents only. The variation of v with molecular weight was
also studied by fractionating PB and determining the v of these different
molecular weight samples. No significant difference in the
v values could be observed in the molecular weight range of 33,000
to 350,000.
