| Outline of Final Research Achievements |
Biodegradable polymers have been developed as green materials. However, when they are used for a long time, long-term stability is important and biodegradability is undesired. Polyamide 4 (PA4) is a biodegradable polymer that can be produced from biomass. Various functional groups were introduced to biodegradable polymers (PA4 and PCL). Hydrophobic groups like long-chain fatty acid as a terminal group suppressed biodegradability of polymers. Adding hydrophilicity with methylolation accelerated biodegradation even if the polymer suppressed biodegradability by long-chain fatty acid terminal. The alteration of the hydrophobicity of the polymers was directly related to the suppression of the biodegradability. Polymers that suppressed biodegradability degraded with surfactants.
