    Abstract: Formulations for producing modified bio-based polymers, especially bio-based polyesters like PLA and/or biodegradable polymers like PBAT, include at least one organic peroxide and at least one bio-based reactive additive. The at least one organic peroxide and/or the at least one bio-based reacted additive are capable of reacting with a bio-based polymer and/or biodegradable polymer to produce the modified bio-based and/or modified biodegradable polymer. The modified bio-based and/or modified biodegradable polymers have improved properties compared to non-modified bio-based and/or biodegradable polymers. The improved properties may related to processability, especially improved melt strength which results in easier processing while producing foamed polymers, thin films, such as blown film, cast film, tentered film and the like. The improved properties may be related to physical properties such as improved stiffness, toughness or tensile strength.
