The intermediate route of the rate-determining reaction is likely the pathway where the protonation occurs on the oxygen atom (at the initial stage of the reaction) and ring-opening follows. The values of apparent activation energy for the polymerization were 19.0 kcal mol([C]≤1.5×[I]) and...

Reaction Kinetics and Simulation for Solid - state Polycondensation of Nylon 6 A comprehensive model for solid - state polymerization of nylon 6 has been developed. Considering the reactive end group - to - end group distance distribu... L Li,C Wang,L Dai,... - 《》 被引量: 44发表: ...
The reaction was carried out at three different temperatures and the overall activation energy was computed. The kinetic data and other evidence indicate that the overall polymerization takes place by a radical mechanism. A suitable kinetic scheme has been suggested....
The optimization involves the minimization of two objective functions, namely the reaction time, tf. and the concentration of the undesirable cyclic dimer in the product, [C2]f, The final monomer conversion, convf, and the degree of polymerization of the final product, 渭nf, are constrained to...
