The two Vinylic reaction sites also account for one unsaturated reaction site should addition reaction be considered.
In this investigation, the hybrid films were obtained by the epoxy-amine addition reaction, followed by hydrolysis and condensation reactions of trifunctional alkoxysilane precursors, catalyzed by dibutyltin dilaurate, which led to a HSPi network, or those also containing PDMS, HPPi, as illustrated in Fig.
Figure 4 reveals that the addition reaction of bromine to SBR is divided into three steps.
Therefore, when compared with conventional heating process, the addition reaction with the help of MI can proceed in a controlled manner with greatly enhanced reaction rate.
It is also possible that the chain addition reaction is terminated by the impurities existing in the plastisol.
Thus, a number of hydroxyl groups undergo nucleophilic addition reactions with epoxide and anhydride, resulting in ring cleavage and the formation of increased crosslinking networks (26-30).
In other words, the termination reaction rather than the addition reaction dominates the shear viscosity of g-PE.
As a result of the epoxy and BMITB networks formed and the consumption of DDS, the Michael addition reaction between DDS and BMITB would not be significant (15), and thus the corresponding heat enthalpy may be too low to be observed in the DSC curve.
The synthetic method for organic-phosphorus modified epoxy oligomers via ring-opening addition reaction of binaphthyl epoxies and DEP was summarized in Scheme 1.
The addition reaction between C = C and the isopropylbenzene oxygen radical is considered to represent the curing reaction of methyl vinyl SR (26), (29).
The urethane reaction is an addition reaction between a hydroxyl group and an isocyanate as shown in figure I.
These are produced by either addition reaction of primary radicals to double bonds in NBR or hydrogen abstraction from methylene carbon atoms by primary radicals in HNBR.
The new products are solvent-free and cure by a platinum-catalyzed addition reaction.
In general, a combination of an epoxy resin and a primary amine leads to two principal reactions of (a) the addition reaction of a primary amine hydrogen to an epoxy group to form a secondary amine and (b) the addition reaction of an amine hydrogen in the secondary amine to another epoxy group to create a tertiary amine [21, 22],
The technology uses a cross-linking chemistry which is highly specific, does not generate any heat and is an addition reaction, meaning that no chemicals are released during the polymerisation process.
