Chlorohydrin rubber, the epichlorohydrin homopolymer, industrial product, with Mooney viscosity M[L.
At room temperature, 100 phr chlorohydrin rubber was masticated on an open mill ([PHI]160 mm) for 2 min and then 0.
The epoxidation reaction of a polyol with epichlorohydrin is very well known (1, 2), and it occurs in two steps; 1, Formation of an intermediate chlorohydrin and 2 dehydrohalogenation to form the glycidyl ether
Taking into account the rate constants obtained, a plot of the chlorohydrin concentrations [Cl.
3, which shows the evolution of reaction, it can be observed that the concentration of chlorohydrin [Cl.
The next step leads, by dehydrohalogenation of chlorohydrins [Cl.
The mechanism shown in Step 1 explains the chlorohydrins formation (6).
From these results obtained, we can predict the chlorohydrins formation under different conditions.
A reaction mechanism for the reaction between ECH and TMP which implies chlorohydrins formation is proposed.
