Nanocomposite polymeric materials based on organoclay

Investigations are presented to identify the conditions of formation nanocomposites based on isotactic polypropylene (PP), maleinized PP (PPMA) and their mixtures with modified montmorillonite, Cloisite 20A (MMT Cloisite 20A). The conditions for the formation of exfoliated and intercalated nanocomposites were determined depending on the Cloisite 20A concentration and the PP/PPMA composition ratio. An increase in the modulus of elasticity for exfoliated nanocomposites by more than 40% was found while maintaining the relative elongation at break.
