Wet-Dry Cycling Delays the Gelation of Hyperbranched Polyesters: Implications to the Origin of Life

open access: yesLife, 2019
In extant biology, biopolymers perform multiple crucial functions. The biopolymers are synthesized by enzyme-controlled biosystems that would not have been available at the earliest stages of chemical evolution and consist of correctly sequenced and/or ...

Topology-controlled hyperbranched polyesters enable balanced soy adhesive strengthening and toughening

open access: yesIndustrial Crops and Products
Soy protein (SP) adhesive have garnered significant attention due to their renewability and environmental friendliness. However, their inherent limitations—particularly poor water-resistant bonding strength and pronounced brittleness of cured adhesive ...

Structural, thermal, rheological, morphological and mechanical properties of polypropylene functionalized in molten state with maleinized hyperbranched polyol polyester

open access: yes, 2019
In a previous study, we realized the functionalization of polypropylene (PP) with maleinized hyperbranched polyol polyester (MHBP) by using dicumyl peroxide (DCP) as an initiator for obtaining the PP-g-MHBPs.

Influence of an hyperbranched aliphatic polyester on the cure kinetic of a trifunctional epoxy resin

open access: yes, 2008
The influence of an OH-terminated hyperbranched aliphatic polyester on the reaction kinetics and rheology of a trifunctional triglycidyl-p-aminophenol (TGAP) epoxy resin cured with an aromatic amine, i.e., diamino- diethyltoluene (DETDA), was ...

Functionalization in solution of polypropylene with a maleinized hyperbranched polyol polyester: Structural, thermal, rheological, and mechanical properties

open access: yes, 2018
The functionalization of polypropylene (PP) with a maleinized hyperbranched polyester polyol (MHBP) was performed in solution to obtain PP-g-MHBPs. The degree of functionalization (FD) increased with MHBP and dicumyl peroxide (DCP) contents, but the ...
