Model of hyperbranched polymers formed by monomers A2 and Bg with end-capping molecules

Acyl Poly(Glycerol‐Succinic Acid) Oligoesters: Synthesis, Physicochemical and Functional Properties, and Biodegradability

“…While these behaviors are relatively well documented in the case of polysoaps and macrosurfactants [12], more complex architectures have received less attention. Nevertheless, branched polymers have also attracted considerable attention in recent years in the field of macromolecules [13][14][15][16][17][18][19][20][21].…”

“…1. The synthesis was carried out under off-gelation conditions in order to avoid the formation of an insoluble solid tridimensional network [20,21], which is incompatible with the targeted surfactant applications. Acyl-grafted poly(glycerol-succinate) surfactants were characterized by nuclear magnetic resonance (NMR), acid values and size exclusion chromatography.…”

Preparation and properties of addition curable silicone resins with excellent dielectric properties and thermal resistance

“…But unlike the well‐investigated classical hyperbranched polymers produced from AB n ‐type monomers, the precise definition of the structure of hyperbranched polymer from A 2 + B 3 route is still difficult today [27]. In light of the method reported by Cheng et al [9], the peaks in the 29 Si NMR spectrum contributing to the signals from T, L, and D units of EHFHPSi can be assigned (see Fig. 6).…”

“…And also, EHFHPSi serves as both effective diluent and cross‐linking agent, simplifying the preparation process. It was synthesized by A 2 + B 3 [8, 9] approach and end‐capped by HMDS, which has obvious advantages such as the wide commercial availability of bi‐ and tri‐functional monomers [10–14], and the effective controllability of the structure and properties of the resultant hyperbranched polymers [15, 16]. EHFHPSi possesses both peripheral and interior Si‐H groups, increasing the cross‐linking points and thus integrated property of the resultant resins [17].…”

Photoluminescence study of tetra-dendron dendrimers derived from ethylenediamine cores and di-dendron dendrimers derived from mono-Boc-protected ethylenediamine cores

“…There has been growing interest among researchers about dendritic polymers, including dendrimers [1][2][3], dendrons [4][5][6], dendrigrafts [7,8] and hyperbranched polymers [9][10][11]. Dendrimers, with explicit symmetry and high density of functional terminals, are morphological architectures differing from typical polymers.…”
