In-situ Compatiblization of Modified Recycled-PLA/ PBAT blends withImproved Mechanical and Rheological Properties

The mixing sequence of Recylced-PLA/PBAT blends using Joncryl chain extender shows an impacton the compatibility of the blend. The Joncryl and PBAT are reactive blended first, followed bymixing with Recycled-PLA, which is most advantageous to produce a substantial amounts ofbranched copolymers rPLA-g-PBAT at the interface for selected blends. The considerableimprovement of interfacial compatibility promotes the stress transfer from the matrix to the dispersedPBAT phase, leading to the increment of tensile and rheological properties.
