For all polymer-based materials

polymer processing is required to fabricate them into useful articles with definite sizes

shapes and forms.This paper summarizes the progress in polymer processing and concludes that the emergence of numerous polymer processing technologies has benefited from nature and other material industries

such as solution spinning from spider silk

blow molding from glass blowing

and calendaring as well as solid-phase drawing forming from metal forging.Moreover

to deal with the big challenge of creating high-performance stereocomplexed polylactide (SC-PLA) products from melt-processed poly(L-lactide)/poly(D-lactide) (PLLA/PDLA) blends because of the poor melt stability of stereocomplex (SC) crystallites after complete melting as well as the serious degradation of PLA chains at elevated melt-processing temperatures

we report a new strategy to prepare highly transparent SC-PLA products with excellent heat resistance

mechanical strength

and hydrolytic stability by means of a low-temperature (i.e.

below the melting temperature of the SC crystallites) powder sintering technology inspired by the concept of powder metallurgy.
