Abstract:
1. A polymer nanocomposite comprising: a) a polylactic polymer; and b) a modified phyllosilicate composition comprising a montmorillonite and a modifying agent including hexadecyl trimethyl ammonium cations which are intercalated between the layers of the phyllosilicate, and further comprising acetylcholine or choline cations as a modifying agent; wherein the acetylcholine or choline is present at a concentration comprised from 0.2-0.75 meq/100 g the value of the phyllosilicate cation exchange capacity and the hexadecyl trimethyl ammonium ions are present at a concentration comprised from 5.25-5.80 meq/100 g the value of the phyllosilicate cation exchange capacity; and, wherein the ratio phyllosilicate composition/polylactic polymer is comprised between 0.5:99.5 and 20:80 weight/weight ratio.
