In order to replace silicones in some of their biomedical applications
, e.g. syringe lubrication, implants etc., a series of digermoxanes (R
1R2R3Ge)2O (R=n-alkyl, aryl) were synthesized. These compounds are the
rmally stable oils; their viscosities, depending on the nature of subs
tituents, lie in the range 1-72 cPo (mPa s) at 20-degrees-C.
