[0008]
However, due to the differences in solubility, reactivity (steric hindrance) and reaction rate of terephthaloyl dichloride or isophthaloyl dichloride used in the synthesis of polyamide resins, the amide repeating units derived from terephthaloyl dichloride and those derived from isophthaloyl dichloride The amide repeat units of acid chlorides do not form blocks and rarely polymerize ideally or alternately
[0009] Therefore, there is a limitation that when a block derived from the amide repeating unit of the p-acyl chloride monomer is formed and the crystallinity of the polyamide resin increases, transparency deteriorates due to haze
[0010] In addition, since monomers used for synthesizing polyamide resins are polymerized in a state dissolved in solvents, it is difficult to ensure sufficient molecular weight of the finally synthesized polyamide resins due to deterioration caused by moisture or hybridization with solvents. Level

preparation example 1
[0321] In a 1000 mL 4-neck round bottom flask (reactor) equipped with a stirrer, nitrogen injector, dropping funnel and temperature controller, charged 549.4 g (2.704 mol) of terephthaloyl chloride (TPC; melting point: 83° C.) and 120.6 g (0.594 mol) of isophthaloyl dichloride (IPC; melting point: 44° C.), and carried out melt kneading at 100° C. for 3 hours, and then cooled at 0° C. for 12 hours to prepare acid chloride (specifically, terephthaloyl dichloride acid chloride and isophthaloyl chloride) complexes.
[0322] Subsequently, the acid chloride complex was ground with a jaw crusher to prepare a powder with an average particle size of 5 mm.
preparation example 2
[0324] An acid chloride complex powder was prepared in the same manner as in Preparation Example 1, except that 569.5 g (2.803 mol) of terephthaloyl chloride (TPC; melting point: 83° C.) and 100.5 g (0.495 mol) of isophthaloyl chloride ( IPC; melting point: 44°C).
