METHOD FOR PREPARING FUNCTIONALISED POLYALKYLENIMINES, COMPOSITION CONTAINING SAME AND USES THEREOF

摘要

The present invention relates to a process for preparing functionalized polyalkyleneimines which are useful for formulating nucleic acids intended to be transfected into cells. This process consists in treating polyalkyleneimines with a functionalized hemiacetal in the presence of titanium (IV) isopropoxide and sodium borohydride.
