Polyalkylenimine

Anion-exchange resins prepared from polyalkylenimine, epichlorohydrin, and third components capable of producing crosslinking have larger life times than is possible with polyalkylenimine and epichlorohydrin alone . Such useful third components include phenol, resorcinol, and aldehydes. 

Polyalkylenimines (PAIs) are a class of cationic polymers that have a generalised structure with secondary or tertiary amines in the main separated by all lene spacers, as shown in Scheme 2.1. Due to the presence of the nucleophilic amine groups in the polymer backbone, their synthesis is more complicated compared to simpler vinyl based polymers. This chapter will focus on the synthesis of the PAIs, their physical properties and a short review of applications, focusing on gene delivery. This chapter will only cover PAI homopolymers and excludes the convoluted area of block copolymers, as this is worth a full review by itself. 

The object of this work is to combine the two ideas of activation of the reaction and as3mrmetric selection in the presence of optically active polymers. For this purpose, optically active polyepichlorohydrin with optically active amine side chain, and optically active linear polyalkylenimines were chosen, and the activity was studied.
