Samples of polysiloxaneurethaneurea elastomers were prepared by moisture-curing of the siloxaneurethane prepolymers terminated with NCO groups at 25oC and 50% R.H. Prepolymers were synthesized from polysiloxanediols of different chain length and diisocyanates using different NCO/OH molar ratio. Sterillisation of samples was made using 28 MeV E-beam or gamma rays to reach 28kGy dose.
