Biodegradable plastics, like aliphatic polyester, are getting popular as eco-friendly alternatives to regular plastics. However, it has drawbacks in its low mechanical and thermal properties. This experiment aims to improve these properties by adding amide to the polyester. First, we made nylon salt by combining Adipic acid and 1,4-Butanediol to enhance reactivity. Then, aliphatic poly(ester amide)s were created through transesterification and melt polycondensation reactions. Testing different amide ratios showed that higher ratios improved mechanical and thermal properties due to stronger hydrogen bonding. Additionally, composting tests demonstrated that all samples decomposed within 20 weeks. Consequently, We have succeeded in synthesizing highly biodegradable poly(ester amide)s with excellent mechanical properties that surpass commonly used biodegradable polymers. This study has the potential to be a breakthrough material that could replace commercial biodegradable plastics.
