Abstract
Polylactide (PLA) is a promising material, with favorable modulus, renewable sources, and biodegradability. However, its low extension at break (4-7 %) and toughness (notched Izod, 26 J/m) limit its applications [1]. PLA toughening has been the subject of recent reviews [1,2], and is the basis for several commercial products. This work aims to increase PLA toughness using rubbery linear low density polyethylene (LLDPE), glycidyl methacrylate functional PE compatibilizer (EGMA), and novel catalysts that promote copolymer formation at the interface of immiscible blends of PLA and EGMA/LLDPE. Droplet size was reduced from 2.7 μm to 1.7 μm with addition of 5 wt% EGMA, and further to 1.0 μm with the addition of cobalt octoate catalyst. Extension at break of 200 % is achieved with only 5 wt% reactive compatibilizer, 15 wt% LLDPE, and 0.01 M cobalt octoate.
