iar,i,j,k,l,m,n,o] is attributed to the addition reaction
, where indexes i, j, and k represent the alkoxy radical substituents, whereas indexes l, m, n, and o represent the substituents of the unsaturated reaction site.
Organic-inorganic hybrid films were obtained by an epoxy-amine addition reaction
followed by hydrolysis/condensation reactions of the alkoxysilane end-groups.
25 ppm are the characteristic peaks, which is the basis of our study to follow the chemoselectivity of addition reaction
23] investigated the chemistry about the curing of bifunctional epoxy resins by amine hardeners and found that a combination of an epoxide and a primary amine leads to two principal reactions; (1) the addition reaction
of a primary amine hydrogen to an epoxy group to form a secondary amine and (2) the addition reaction
of an amine hydrogen in the secondary amine formed by the reaction (1) to another epoxy group to create a tertiary amine.
Therefore, actually all the MI assisted addition reaction
The reactions involved in the crosslinking of the plastisol include the addition reaction
of TAC molecules and the graft reaction of TAC onto the PVC chains.
In this work, the homogeneous model system involves a simple addition reaction
mechanism leading to an exothermic reaction between epoxide and anhydride activated groups.
5 suggestes its activation energy to be negative, interpreting that the addition reaction
(c) is faster or the termination reaction (e) is slower at lower temperature in the elementary reactions.
The reactions involved in the crosslinking of the plastisol have been the addition reaction
of and the graft reaction of PVC onto TMPTMA chains or networks.
g] is attributed to the epoxy-amine network formed by the addition reaction
between amino groups in DDS and oxirane groups in ECN (see Fig.
The addition reaction
of DEP and epoxy was carried out under the temperature range of 120-160[degrees]C, where quaternary ammonium was used as catalyst.
As for pentamethylvinyldisiloxane, an intermediate complex (M2) between the isopropylbenzene oxygen radical and the pentamethylvinyldisiloxane (2a) forms first when isopropylbenzene oxygen radical approaches to pentamethylvinyldisiloxane and then the addition reaction
occurs through TS2.
