1,3-bis(3-glycidoxypropyl)tetramethyldisiloxane Chemical Properties, Uses, Production

Uses

1,3-Bis(3-glycidyloxypropyl)tetramethyldisiloxane can be used:

  • As a starting material to synthesize functional poly(siloxane amine)s via an amine-epoxy click polymerization for material and biological applications.
  • To prepare polymer electrolyte membranes (PEM) for fuel cell applications.

Synthesis

1,1,3,3-Tetramethyldisiloxane and 1.1 equiv of allyl glycidyl ether (calculated to each Si-H group) were placed into the reaction vessel and heated up to 90 °C. Then the appropriate amount of [{Rh(OSiMe3)cod}2] (in the ratio 10-5 mol per mol Si-H) was added as a catalyst, and the reaction was continued for the next 2 h to give a crude product 1,3-bis(3-glycidoxypropyl)tetramethyldisiloxane.
