As a result, Table 5 shows that by increasing the PEG content, the degree of crystallinity increases by 90% compared to neat PLLA and by up to 40% compared with the composite having 10 wt.% silica.

Webis the chain density. The concept of packing length unites the volume filling and conforma-tional characteristics of a polymer into a chain-length-independent parameter. The magnitude of p can be viewed as representing the relative thickness of a polymer chain.6 The notion of packing length has facilitated the development5–7 of correlations ...
WebJan 18, 2013 · Commercial membranes have been largely derived from polymers with moderately rigid chains that pack closely to create small intermolecular spaces (or "free volume") that impart moderate to high gas selectivity. However, their relatively low gas permeability slows down the separation processes.
