摘要： 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° 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. wherein R1 is a C3 to C12 linear, branched or cyclic alkylene group.

摘要： A copolymerized polyamide resin includes a polymer of a monomer mixture comprising a dicarboxylic acid component comprising adipic acid and a dicarboxylic acid represented by Formula 1, wherein each R1 is independently a C1 to C5 alkyl group and a is an integer from 0 to 4, and a diamine component comprising m-xylene diamine and a diamine represented by Formula 2, wherein A is a single bond or a C1 to C10 hydrocarbon group, R2 and R3 are each independently a C1 to C5 alkyl group, and b and c are each independently an integer from 0 to 4, wherein the copolymerized polyamide resin has a difference between a melting temperature (Tm) and a crystallization temperature (Tc) of about 50° C. or more. The copolymerized polyamide resin may have excellent heat resistance and reduced or no gel generation and yellowing phenomenon in a molding process.

摘要： 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.
