A new synthesis process of polymer materials based on vegetable oil has been developed. First, linseed was thermally polymerized in bulk at 300 °C under an inert atmosphere. Next, the obtained stand functionalized a two-step one-shot without solvent order to graft some photopolymerizable groups. The first step consisted reaction with maleic anhydride 220 grafted groups were then used second as anchor for grafting 2-hydroxyethylmethacrylate room temperature. Finally, prepared by UV-curing...
Herein, we report the use of photoinitiated thiol–epoxy chemistry for preparation a new biosourced self-healing coating.
A set of commercial (meth)acrylic resins was photopolymerized under identical irradiation conditions and evolution their refractive index monitored as a function double bond conversion.Initial values ranged from 1.4445 to 1.5454 then linearly increased with conversion long the material not in glassy state.This increase related an density arising during polymerization.Final 1.4804 1.5632.The knowledge its photocuring is indispensable, particularly elaborate composite materials (polymer matrix...
In this work, we describe the synthesis of a new dimethacrylate phosphonate monomer by condensation methacryloyl chloride with diol resulting from radical addition allyldiethyl 3-mercapto propane-1,2-diol. The photochemical polymerization was first studied as function reaction temperature. optimal conversion photopolymerization 63% at 70°C. This is less reactive than commercial polyether Bisphenol A, that have used for copolymerization. mechanical and thermal properties final material were...
UV polymerizations in the presence of a photobleachable initiator are studied. The photoinitiator concentration vs time and radiation intensity evolution within sample calculated according to rate equations. Polymerization temperature profiles inside assuming steady-state conditions. Thermal boundary conditions chosen for orthopedic applications. polymerization is then investigated under range photoinitiation access ability form thick materials. Theoretical results indicate that both cure...
Several theories have been proposed concerning the stand oil reaction but no precise scheme has described. In this work, of linseed was characterized in order to determine nature products formed during reaction. Using complementary analytical techniques (more especially NMR and mass spectrometry), existence two different reactions demonstrated: Diels–Alder addition between fatty acid chains a methylene radical on double bonds, followed by combination or elimination reactions.
Abstract Graft polymerization of acrylic acid from monomer solutions in water or bulk onto low‐density polyethylene film substrate was carried out by the method continuous process under UV radiation. Effects nature photoinitiator on grafting first studied. One PI 2 and two 1 photoinitiators were used. Benzophenone then retained for following study. The influence concentration investigated determining kinetics grafted polymer amount. A study surface wetting morphological structure a system as...
