| description | The present invention relates to a cavity-preventing type reactor and a method for fabricating a preform for a plastic optical fiber using the same. Particularly, the present invention relates to a cavity-preventing type reactor comprising: (a) an introduction part (10) having a reactant inlet (11) through which a reactant is introduced into the whole reactor; (b) a reaction part (20) which is adjacent to the introduction part through a blocking wall (32) and has a flow path (21), through which the reaction part (20) is connected with the introduction part (10), at the center of the blocking wall; and (c) one or more cavity-preventing structures (30) which exist between the flow path (21) of the reaction part (20) and the reactant inlet (11) of the introduction part (10), and has one or more flow paths through which the reactant flows from the introduction part (10) to the reaction part (20), for preventing a cavity developed from the reactant inlet (11) of the introduction part (10) from extending to the reaction part (20) during rotation of the reactor. It is needless to charge monomer or prepolymer additionally into the vacancy formed after polymerization so as to compensate a volume shrinkage due to polymerization of the monomer under the rotation of a reactor. |
