'Quat-Primer' polymers based on b-PEI and their application in composites
… ring opening reaction of various functionalized five-membered cyclic carbonates and epoxides couplers with branched polyethylenimine (b-PEI). Furthermore, depending on the functionality introduced in the polymer, the application of these modified polymers (i) as primers in carbon fibre - epoxy …

Multifunctional chitosans obtained via polymer-analogous reaction with functional five-membered cyclic carbonates
… biocides. In the preparation of these compounds carbonate couplers play an important role. Therfore different carbonate couplers were developed and evaluated by reaction with amines. Chitosan is a biocompatible natural polyamine, which is obtained from chitin - the second most abundant …

From cyclic carbonate bifunctional couplers to amphiphilic poly(ethylene imine)s
… in this thesis are mostly bearing at least one five-membered ring carbonate. These bifunctional couplers were suitable for the selective combination of two functional primary amines. Via addition or substitution reactions of bifunctional couplers with functional amines, functional couplers with …
