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 ...
Thermosetting polymers
(Wiley, 2013)
Examples of thermosets synthesized by step-growth or chain-growth polymerizations are described. Structural transformations (gelation, vitrification) taking place during network formation, are analyzed using a conversion ...
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 ...
