Tailor-made and chemically designed synthesis of coumarin-containing benzoxazines and their reactivity study toward their thermosets
(John Wiley & Sons Inc, 2016-05)
Coumarins are used as a natural renewable resource to synthesize coumarin-containing benzoxazine resins. The coumarin-containing benzoxazines are fully characterized in terms of their chemical structure by Fourier-transform ...
Bio-based thermosetting epoxy foams: mechanical and thermal characterization
(American Chemical Society, 2015-07-06)
Thermosetting epoxy foams were synthesized by replacing the commercial synthetic epoxy resin by a biogenic epoxidized vegetable oil. Foam formulations were developed avoiding the use of amine hardeners, organic volatile ...
Synthesis and characterization of new thermosetting polybenzoxazines with other functional groups in the network
(Journal of Polymer Research, 2018)
Structural properties of vegetable oil thermosets: Effect of crosslinkers, modifiers and oxidative aging
(Pergamon-Elsevier Science Ltd, 2020-02)
The present work is focused on the study of the formulation effect of cationically polymerized vegetable oil thermoset on their aging behavior. Toward this aim, tung oil-based biopolymers were prepared using different ...
Synthesis and characterization of new thermosetting polybenzoxazines with other functional groups in the network
(Springer, 2018-05)
In this work, novel thermosetting systems of high performance based on multi-functional benzoxazines were developed. First, 3-(2-hydroxyethyl)-3,4-dihydro-2H-1,3-benzoxazine (BzOH) and bis(3-(2-hydroxyethyl)-3,4-dihydro-2H-1,3- ...
Synthesis and characterization of an epoxy based thermoset containing a fluorinated thermoplastic
(John Wiley & Sons Inc, 2007-10-01)
A novel fluorinated thermoplastic (FT) was synthesized from diglycidyl ether of bisphenol A (DGEBA), and 3-(trifluoromethyl)aniline. FT was found to be miscible with DGEBA as shown by the existence of a single glass ...
Design of thermosetting polymeric systems based on benzoxazines modified with maleic anhydride
(John Wiley & Sons Inc, 2018-05)
A novel benzoxazine (BzPFA) with carboxylic acid groups in its structure was synthesized in a two-step process. First, BzPOH monomer was obtained from bisphenol A, paraformaldehyde, and ethanolamine with an initial molar ...
Composites from PMMA modified thermosets and chemically treated woodflour
(John Wiley & Sons Inc, 2003-04-07)
The mechanical behavior of composites made from woodflour and a modified thermoset unsaturated polyester resin has been examined. Polymethylmethacrylate (PMMA), a common low profile additive (LPA), was used as the matrix ...
Thermodynamic analysis of the reaction-induced phase separation of solutions of random copolymers of methyl methacrylate and N, N-dimethylacrylamide in the precursors of a polythiourethane network
(John Wiley & Sons Inc, 2006-10)
Poly(methyl methacrylate) and random copolymers of methyl methacrylate (MMA) and N,N-dimethylacrylamide (DMA) containing 7.5, 15, or 20 wt % DMA were dissolved in a stoichiometric mixture of m-xylylene diisocyanate and ...
Poly(methyl methacrylate)-modified vinyl ester thermosets: Morphology, volume shrinkage, and mechanical properties
(John Wiley & Sons Inc, 2007-12)
Thermoset materials obtained from styrene/vinyl ester resins of different molecular weights modified with poly(methyl methacrylate) (PMMA) were prepared and studied. Scanning electron microscopy and transmission electron ...
