    摘要: The present invention relates to compostable and biodegradable thermoplastic compositions comprising a thermoplastic polymer, a hydrolytically unstable antioxidant, a pro-oxidant, an accelerator, and a property modifier. The hydrolytically unstable antioxidants effectively prevent the thermoplastic polymer from breakdown by oxidative or thermal degradation under dry conditions. Under wet conditions, the hydrolytically unstable antioxidant becomes ineffective and the thermoplastic polymers breakdown to low molecular weight materials.
