Abstract
Chain architecture is an influential parameter in melt processing of polymeric material. In this study effect of different chain structures on polylactide (PLA) film blowing process and on the final film properties was investigated. Blends of linear PLA with three branched poly(L-lactide)s with 4-arms star shaped, comb like and hyper branched structures were prepared by twin screw extruder. In another series of blending, poly(D-lactide) of these branched structures were used to obtain stereocomplex crystal. Operating window of blends were determined in a series of film blowing process experiments with different blow up and take up ratio and results were compared to linear PLA as a reference. Moreover, different characterization techniques were applied to determine the properties of produced films. It was found that addition of branched architecture and presence of stereocomplex in a linear PLA matrix result in a greater operating window for film blowing and improve mechanical and crystallization properties of blown films.
