With a total of 2 patents to his name, his work has garnered attention for its innovative approaches and practical applications.

Latest Patents

Bang's latest patents include a crystalline polyamide ester resin and a method for preparing the same. This crystalline polyamide ester resin is synthesized through the copolymerization of a dicarboxylic acid component, a diamine component, and a cyclic aliphatic diol component. The resulting resin exhibits a structure where the dicarboxylic acid moiety, diamine moiety, and cyclic aliphatic diol moiety are repeated. The molar ratio of the diamine component to the cyclic aliphatic diol component is maintained between 80 to 99:1 to 20. This innovative resin boasts a melting point ranging from about 280°C to about 320°C and a crystallization temperature from about 260°C to about 290°C, showcasing excellent heat resistance, discoloration resistance, and moldability.

Another significant patent involves a polyamide resin that contains both an amine group and a carboxyl group. The concentration of the amine group is approximately 200 to 300 µeq/g, which is two to six times higher than that of the carboxyl group. This unique formulation provides the polyamide resin with exceptional long-term thermal stability.
