Silicone modified epoxy resins with good toughness, damping properties and high thermal residual weight
Abstract In this research, a series of epoxy-silicone copolymerswere prepared from methyl phenyl silicone intermediates (PMPS) with a bisphenol A type epoxy resin (E-51) by condensation with dilaurate dibutyltin acting as catalyst. The chemical structure of the siloxane-bridged epoxy resin was characterized by Fourier transform infrared spectroscopy (FTIR), 1H-NMR and an epoxy equivalent weight ...

Effect of borates on thermal degradation and flame retardancy of epoxy resins using polyhedral oligomeric silsesquioxane as a curing agent
A series of flame-retardant epoxy resins containing boron and silicon were obtained through a crosslinking reaction, using tris (2-hydroxypropyl) borate (THPB) together with octaaminophenyl POSS(OapPOSS) as the curing agents. The limiting oxygen index (LOI) reached 30.5% when the contents ofboron and silicon in the cured system were 1.5% and 0.5%, respectively, indicating that THPB and OapPOSS exh...

31. Sustainable epoxy resins derived from plant oils with thermo- and chemo-responsive shape memory behavior
Sustainable epoxy resins derived from plant oils with thermo- and chemo-responsive shape memory behavior
Shape-memory epoxy resins were synthesized using plant oils and cellulose nanocrystals (CNCs). Epoxidized soybean homopolymers (PESBMA) were grafted from CNCs using surface-initiated atom transfer radical polymerization (SI-ATRP). The polymer grafted CNCs were combined with P(ESB...

(ACS Sustain. Chem. Eng.) Hexahydro-s-triazine: A Trial for Acid-Degradable Epoxy Resins with High Performance
Hexahydro-s-triazine (HT) derivatives are acidsensitive compounds. 4,4′,4″-(1,3,5-Hexahydro-s-triazine-1,3,5-triyl) tris(N-(2-aminoethyl) benzamide) (HT-A) bearing three amino groups was synthesized as a curing agent to prepare the acid-degradable epoxy resin. The chemical structures of HT-A and its precursor were confirmed by 1H NMR and 13C NMR. The synthesized HT-A, as well as the commer...

(Macromolecules) Vanillin-derived High-performance Flame Retardant Epoxy Resins: Facile Synthesis and Properties
Lignin derivative vanillin when coupled with diamines and diethyl phosphite followed by reaction with echichlorohydrin yields high-performance flame retardant epoxy resins. Biorenewable and environment-friendly flame retardant alternatives to bisphenol A epoxy resins (having plenty of applications such as coatings, adhesives, composites, etc.) have captured great attention due to their ecologica...

Simultaneously increasing impact resistance and thermal properties of epoxy resins modified by polyether-grafted epoxide polysiloxane
In this paper, polyether-grafted-epoxide polysiloxane (FEPMS) was synthesized via hydrosilylation among poly(methylhydrosiloxane) (PMHS), allyl polyoxyethylene polyoxypropylene ether (F6) and allyl glycidyl ether to modify Diglycidyl Ether of Bisphenol A (DGEBA). The morphology, thermal properties, and toughness of all cured samples were investigated by scanning electron microscopy (SEM), differ...

Morphologies and Mechanical and Thermal Properties of Epoxy Resins Modified by A Novel Polysiloxane Capped with Silane Coupling Agent, Epoxide and Imino Groups
A novel polysiloxane capped with silane coupling agent, epoxide, and imino groups (AGPMS) was synthesized to modify the diglycidyl ether of bisphenol-A (DGEBA). The chemical structure of AGPMS was confirmed using Fourier transform infrared (FT-IR), (29)Si NMR, and (13)C NMR. The toughness of the epoxy resin, in terms of impact strength and fracture toughness, was improved by introducing AGPMS, w...

(Prog. Org.Coat.)Synthesis of bio-based unsaturated polyester resins and their application in waterborne UV-curable coatings
In this paper, three bio-based unsaturated polyesters were synthesized from itaconic acid and different diols which could be derived from renewable resources. Their chemical structures were confirmed by FT-IR, 1H NMR and acid value as well as hydroxyl value. Waterborne UV curable networks based on these polyesters were manufactured and their mechanical properties, thermal stability and coating p...
