38.Two Strategies to precisely tune the mechanical properties of plant oil-derived epoxy resins
During recent years, the development of mechanically robust epoxy resins from natural abundant plant oils is gaining more and more attention.
Herein, two strategies were developed to precisely tune the microstructure of
plant oil-derived epoxy polymers and mechanical properties of their thermosets.
In strategy 1, plant oil-derived epoxy polymers (EPs) with varied densities of
epo...

Influence of solubility parameter difference between monomer and porogen on structures of poly (acrylonitrile-styrene-divinylbenzene) resins
ABSTRACT: In this work, the acrylonitrile (AN)-styrene (St)-divinylbenzene (DVB) resin was synthesized via suspension polymerization in the presence of inert porogens as diluent. The relationship of the solubility parameter (SP) of the materials and the porous properties of the resin was investigated. These porous spherical resin particles (0.25–0.84 mm) can be used as precursors of amidoxime r...

Preparation of damping structural integration materials via the formation of nanostructure in triblock copolymer modified epoxy resins
ABSTRACT: Amphiphilic triblock copolymer Poly(ε-caprolactone)-block-polydimethylsiloxane-block-poly(ε-caprolactone) (PCL-b-PDMS-b-PCL, LDL) was synthesized via the ring-opening polymerization of ε-caprolactone in the presence of hydroxyl-terminated polydimethylsiloxane
(HTPDMS) and was utilized to modify epoxy. The tensile strength and elongation at break were simultaneously enhanced when...

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...
