Dendritic Polyurea Polymers

Abstract

Dendritic polymers, subsuming dendrimers as well as hyperbranched or highly branched polymers are well established in the field of polymer chemistry. This review article focuses on urea based dendritic polymers and summarizes their synthetic routes through both isocyanate and isocyanate-free processes. Furthermore, this article highlights applications where dendritic polyureas show their specific chemical and physical potential. For these purposes scientific publications as well as patent literature are investigated to generate a comprehensive overview on this topic.

Dynamic Networks that Drive the Process of Irreversible Step-Growth Polymerization

“…The structural formulas of the monomers together with their AB representations that define the underlaying network topology are displayed. The list of polymers include: polyester 59 , branched polyurethane 60 , polyurea 61 and polyamide 62 .…”

Synthesis and properties of allyl terminated renewable non-isocyanate polyurethanes (NIPUs) and polyureas (NIPUreas) and study of their photo-crosslinking

“…They are widely used in lacquers, coatings, varnishes and reaction injection molding systems. However, the introduction of branching units alters the intrinsic properties of these polymers and improves their solubility, which can be a benefit for some applications [31].…”

Molecular Weight Determination by Luminescent Chemo–enzymatics

“…This transformation was used to detect urea in urine by a phosphorescence sensor based on manganese doped zinc sulfide QDs . Polyureas are an important class of polymers, with applications in many fields, particularly, emergent polyurea dendrimers and their branched and hyperbranched counterparts . In this work, we investigated the molecular weight determination by enzymatic degradation using polyurea dendrimers as a case study, but linear and crosslinked polymers are envisaged to be suitable materials to investigate using this methodology.…”
