PURPOSE: A coaxial multi-pipe type fluid supplying nozzle is provided to mix two different kinds of polymerizable fluids in a polymerization pipe to make them homogenized. CONSTITUTION: A coaxial multi-pipe type fluid supplying nozzle(10) comprises more than two fluid supplying tubes(1,2), and more than one insulating pipes(3). The fluid supplying tubes supply two different kinds of fluids. The insulating pipes are placed between the fluid supplying tubes in vacuum. The fluid supplying tubes and insulating pipes have the same axis. Vortex generators(2a) are formed on the inner side of the end tip of the fluid supplying tubes except for the innermost fluid supplying tube. |
