Synthesis and Characterization of PTDMS

Poly(methylhydrosiloxane) with M_n = 1900 g/mol (ABCR, Karlsruhe, Germany), Karstedt’s catalyst (platinum complex of 1,3-divinyl-1,1,3,3-tetramethyldisiloxane in xylene, Sigma-Aldrich, St. Louis, MO, USA), 1-tetradecene (92%, Sigma-Aldrich, St. Louis, MO, USA), cross-linking agent 1,7-octadiene (98%, Sigma-Aldrich, Munich, Germany), and n-hexane (99%, Chimmed, Podolsk, Russia) were used for the synthesis of PTDMS. Helium (99.995%), methane (99.99%), ethane (99.95%), and n-butane (99.95%) were used for sorption and permeation measurements.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
