The continuous solid-state polymerization device of the present invention comprises: a feeder for continuously introducing a prepolymer; a horizontal reactor which is connected via a first connecting part to the feeder and receives the prepolymer from the feeder so as to subject same to solid-state polymerization, wherein the reactor itself is rotated; a stirring device which comprises a stirring shaft rotating inside the horizontal reactor, in the direction opposite to that of the rotational axis of the horizontal reactor, and comprises stirring blades joined vertically to the stirring shaft; and a chamber which is connected via a second connecting part to the horizontal reactor and, once the solid-state polymerization has been completed, receives the resulting polymer discharged from the horizontal reactor, and, here, the feeder, the horizontal reactor and the chamber are in a vacuum state. The continuous solid-state polymerization device prevents the formation of prepolymer stagnation zones, and allows solid-state polymerization to take place continuously in the vacuum state without any inert gas.

A continuous solid-state polymerization device according to the present invention comprises: a feeder for injecting a prepolymer continuously; a transverse reactor connected to the feeder via a first connector to receive the prepolymer from the feeder and to perform solid-state polymerization, the reactor itself rotating; and a chamber connected to the transverse reactor via a second connector to receive a polymer, which has been discharged from the transverse reactor, and solid-state polymerization of which has been completed, and to discharge the polymer, wherein the transverse reactor has a demolding coating film formed on the inner wall thereof, and the feeder, the transverse reactor and the chamber are in a vacuum state. The continuous solid-state polymerization device can prevent formation of an interval, in which the prepolymer stagnates, and can perform solid-state polymerization continuously in a vacuum state without using inert gas.

Continuous solid-state polymerization device and method

A polyamide ester resin includes: a repeat unit derived from a dicarboxylic acid; a repeat unit derived from a diamine; and a repeat unit represented by the following Formula 1, wherein the polyamide ester resin has a melting temperature (Tm) of about 280&#xb0; C. or more. The polyamide ester resin can exhibit excellent properties in terms of moisture absorption resistance, heat resistance, discoloration resistance, fluidity and the like by using a cyclic ester.
