Does anyone know where to find the specific heat capacity (cp) of
methylsiloxane (Silikonkautschuk, silicon resin) ? I `d appreciate any help.

No Daniel or is it Bernd. You may have to get the calorimeter out.
search Chem Abs on-line with CA Reg for methylsiloxane and specific
heat capacity
Or you could look in a reference book!!
I wish I'd thought of that-wait a minute I did!

Dear Daniel,
you can also try the CHEOPS software with the Andrey A. Askadskii approach
http://www.millionzillion.com.pl/cheops/home02.htm

It calculates among others the:
Specific heat capacity at 298 for glassy state
Specific heat capacity at 298 K for liquid state
http://www.millionzillion.com.pl/cheops/products03.htm
They also have a large polymer database.

Or go to http://www.dtwassociates.com/ the have some
Polymer design Tools. They also use other methods
(Askadskii,van Krevelen, Bicerano).

----
Without warranty:
Heat capacity of solid polymer at 298 K
Poly(methylsiloxane) [-OSiH(CH3)-] 100,9 J/(mole*K) (calc)
Poly(dimethy siloxane) [-OSi(CH3)2-] 124 J/(mole*K)(calc)
----

With kind regards
