It is possible to obtain a thermoplastic polymer having an effect of remarkably improving the compatibility of the polyester resin and the polyamide resin by carrying out a melt reaction at 10 ° C. for 10 to 240 minutes. If the reaction temperature is lower than 220 ° C, it becomes difficult for the resin to melt, and 2
Thermal decomposition begins when the temperature exceeds 80 ° C. If the time is less than 10 minutes, the reaction between the resins becomes insufficient, and if it exceeds 240 minutes, the reaction no longer proceeds.
