POMS- Polyoctylmethylsiloxane

POMS- Polyoctylmethylsiloxane

(OP)
Hi..partners,

 I am pursuing POMS properties, I have special interest in viscosity x temperature (20-100 Celsius). I am gonna go to use this information to proceed some calculations. If you do not have viscosity information other topics also can help me to predict this viscosity using Van Kravelen Book. I alredy tried  a lot of books, but it was a unsuccessful journey.

a) Tg Glass-rubber transition temperature
b) Mcr Critical molecular mass
c) Mw weight-average molecular mass

 So, I am not an material engineer or even a polymer chemist, maybe this problem is much more complex than I imagine..

 Thanks in advance,

 Shanzon

 PS: The focus of all this is to calculate some parameters to predictions of pervaporative process using membranes of POMS.

RE: POMS- Polyoctylmethylsiloxane

POMS material properties are largely a function of crosslinking and reaction kinetics.  Without data on crosslink density, the other questions are moot.

An intern here wrote a paper in part detailing POMS membranes with c3/c1 properties.  He was from a French university, but other than that I can't remember much.
