摘要： An object of the present invention is to provide a process for producing thermoplastic resin pellets, which realizes production of pellets of uniform shape. Another object of the present invention is to provide an apparatus for producing the thermoplastic resin pellets. The invention provides a process for producing thermoplastic resin pellets, including pressurizing the interior of a vessel holding a molten thermoplastic resin, thereby discharging the resin; forming pellets through solidification and cutting of the resin; and transferring the pellets to a storage container via a pipe by a pneumatic transportation or a suction transportation, wherein the amount of the resin discharged is regulated by controlling the pressure in the vessel so that variation in the difference pressure between the inlet and the outlet of the pipe for transferring the pellets is 10% or less.

摘要： The present invention provides an apparatus for producing thermoplastic resin pellets of uniform shape. The apparatus includes a batch-type polymerization vessel whose inner pressure can be controlled; a pelletizer for cutting a strand-form thermoplastic resin discharged from the polymerization vessel, thereby forming pellets; a pipe for transferring the pellets to a storage container by pneumatic transportation or suction transportation; a pressure differential measuring unit for determining variation in a pressure difference between the inlet and the outlet of the transfer pipe; and a pressure controlling unit for controlling the inner pressure of the batch-type polymerization vessel on the basis of the variation in the measured pressure difference; wherein the inner pressure of the batch-type polymerization vessel is controlled in relation to a pressure loss in the transfer pipe.

摘要： A process for producing a polyamide through direct polycondensation of a diamine component, which contains at least 70 mol % of a xylylenediamine containing at least 20 mol % of paraxylylenediamine, and a dicarboxylic acid component, substantially in the absence of a solvent and using a batch reactor equipped with a partial condenser; the process comprising the following steps: (1) a step of feeding the dicarboxylic acid component into the reactor, and then pressurizing the reactor to increase the inner pressure to a pressure of at least 0.1 MPaG, (2) a step of continuously or intermittently adding the diamine component to the dicarboxylic acid component while the pressure inside the reactor is kept at 0.1 MPaG or more and while the reaction system is kept in a uniform flow state as a whole, (3) after the addition of the diamine component, a step of lowering the pressure inside the reactor to atmospheric pressure or less at a pressure-lowering speed of from 0.1 to 1.0 MPa/hr.
