<p>PURPOSE:To secure a necessary polymerization reaction time for a monomer, and a plasticizing and kneading time for an obtained polymer, by making use of a screw kneading type extrusion molding machine whose extruding screw is constituted of only a compression part and resin melting, kneading and measuring part. CONSTITUTION:A gear pump 32 and two-part liquid mixing and delivery device 33 are arranged respectively on the lower part of vessel 30, 31 and the lower part of the gear pump 32, the bottom becomes a static mixer 34 and the delivery part is inserted into a raw material loading port 35 of an extrusion molding machine. The inside of the extrusion molding machine is provided with vent screws 36 biaxially in the different directions and there is a vacuum deaerating vent hole 37 on the upper part of the screws 36. A molding die 39 is on an end part of the extrusion molding machine. Since an extruding screw is constituted of only a compression part B and metering part C and the same is obtained by diverting an amount of a length of a feed part which has been made necessary so far to the metering part, a plasticizing and kneading period of time for a polymer obtained through polymerization can be taken sufficiently.</p> |
