Antibacterial and compostable polymers derived from biobased itaconic acid as environmentally friendly additives for biopolymers

In this work, a series of antibacterial cationic copolymers derived from bio-sourced itaconic acid was studied as potential biobased active components in biodegradable formulations based on poly(butylene adipate-co-terephthalate) (PBAT) for packaging applications. These copolymers were first charact...
