SILICONE COMPOSITE MATERIAL FOR THE PRODUCTION OF VASCULAR TISSUE REPLICA

摘要

The present invention relates to a composite material, siliconized, and its use as a replica of vascular tissue. This material comprises: - a non woven - silica, and - a crosslinked polymer pr obtained by a hydrosilylation reaction between a first polymer resin rp1 and a second polymeric resin, rp2 in the presence of a catalyst of the hydrosilylation reaction; the resin rp1 comprising a mixture of two polymers p1 - 1 and p1 - 2, and having a viscosity v1 between 500 and 4000 mpa · s, the resin, rp2 comprising a mixture of two polymers p2 - 1 and p2 - 2, and having a viscosity greater than v1 and v2 between 5000 and 60000 mpa.s; the polymers p1 - 1 and p2 - 1, comprising at least two monomer units - (r1hsi - o) - or - (ch2 r1hsi -) -; the polymers p1 - 2 and p2 - 2, comprising at least two monomer units -) - (r2xsi - 0, x being a hydrocarbon-based group containing a double bond c = c; r1 and r2 are, independently of one another, a hydrocarbon group, or a hydrocarbon group, the hydrogen atoms are at least partially substituted
