Orthobaric Liquid Densities for Octamethylcyclotetrasiloxane, Decamethylcyclopentasiloxane, Dimethicone-20, and a Cyclic Poly(Dimethylsiloxane)
The orthobaric liquid-state densities of octamethylcyclotetrasiloxane (292-408 K), decamethylcyclopentasiloxane (302-451 K), and two dimethylsiloxane polymers-one a linear polymer of molecular weight around 1900 (292-470 K) and the other a closely-fractionated cyclic polymer of molecular weight 2935 (302-455 K)-have been determined using a hydrostatic density balance over the temperature ranged quoted. The resulting specific volumes have been fitted to a simple quartic power series in temperature.
