Reactive extrusion of pla
WebFused deposition modeling (FDM) is currently the most popular 3D printing method, where thermoplastic polymers are predominantly used. Among them, the biobased poly ... WebThe reactive extrusion of PLA with chemical modifiers is a complex process, in which both polymer chain scission and chain recombination take place [ 135, 136 ]. Additionally, secondary reactions, such as transesterification [ 126, 137] or homopolymerization [ 138, 139] could happen.
