Organophilic montmorillonite was obtained by the reaction of montmorillonite (MON) and distearyldimethylammonium chloride (DSAC). The modified clay and poly( l-lactide), (PLLA), were solvent-cast blended using chloroform as cosolvent. The structure and properties of the PLLA-clay blends were investi

The dynamic viscoelastic behavior of Poly(l-lactic acid) (PLLA), with molecular weights ranging from 2,000 to 360,000, have been studied over a broad range of reduced frequencies (approximately 1 ฯซ 10 ฯช3 s ฯช1 to 1 ฯซ 10 3 s ฯช1 ), using time-temperature superposition principle. Melts are shown to have
Hydrolysis of poly( L-lactide ) (PLLA) films in 0.01N NaOH at 37ะC was investigated by gel permeation chromatography, differential scanning calorimetry, scanning electron microscopy, and polarizing optical microscopy. The change in molecular weight distribution and surface morphology of PLLA films d
