We discovered that polyisobutylene (PIB)‐based polyurethanes (PIB‐PUs) containing minuteamounts (0.5%) of chemically bound organicallymodifiedmontmorillonite (OmMMT) surprisingly produce films exhibiting improvedproperties. The OmMMT was prepared by reacting sodium montmorillonite (Na+MMT−) with quaternary ammonium salts of a tertiary amine carrying a NH2 functionality. The positively charged

Process are described for the delivery of a polynucleotide to a cell. The process comprises forming a salt stable complex between the polynucleotide and a cationic surfactant. Ternary complexes are also made by associating an amphipathic compound with the binary complex. The resultant complexes are suitable for delivery of the polynucleotide to cells in vitro and in vivo.
