The present invention relates to a method of manufacturing a bladder (2) of thermoplastic gas-tight polymer of a composite tank (1) type IV, and to a type IV tank (1) that can be obtained by process. The method of the invention comprises a step of polymerizing a precursor monomer of said thermoplastic polymer into said polymer thermoplastic in a rotating mold heated to a working temperature greater than or equal to the melting temperature of said monomer and less than the melting temperature of said polymer so as to form said bladder (2) by polymerization of said monomer coupled to rotational molding and without fusion of thermoplastic polymer obtained. |
