1. one kind biocompatiblely is embedded with hydrophilic segmental multipolymer film, and the main chain of the multipolymer of said multipolymer film comprises:

  • (a) at least one hard segment of 10 weight %~

    45 weight %;

    (b) soft chain segment of 55 weight %~

    90 weight %, said soft chain segment comprises;

    (i) account for the oxygen-permeable YSR 3286 soft chain segment of the 5 weight %~

    25 weight % of soft chain segment gross weight;

    (ii) account for the wetting ability soft chain segment of the 5 weight %~

    25 weight % of soft chain segment gross weight, described wetting ability soft chain segment is to gather (oxyalkylene) chain, and the chemical formula of its repeated structural unit is O (CH 2) N, N<

    4 wherein;

    With (iii) account for the hydrophobicity polycarbonate soft chain segment of Biostatic of the 50 weight %~

    90 weight % of soft chain segment gross weight.
