Dear Bilal,
The refractive index of (C2H6OSi)n (Polydimethylsiloxane, PDMS) in the wavelegth of 0.7 µm is 1.458 .
for more theoretical information please read this paper:

I understand this question was posed more than a year ago. For others that stumble on this thread, a good resource is:
https://polymerdatabase.com/polymer%20physics/Refractive%20Index.html
It has the beginnings of what one would need to calculate the RI of a block copolymer as well as a graft composites blends and semi crystallin polymers.
Hope this helps!
Bilal Naqvi It's the volume fractions of the components and their respective RI's that need to be considered. This is a consequence of Mie theory. You'll see incorrect postings that it's weight or molar proportions that need considerarion. More information in:
