Development of Michael Addition Polymerization Kinetics Model
NH] represent the Michael addition polymerization rates corresponding to the polymerization of the -C=C-group of BMI with the >[CH.
Kinetic Scheme for the Free Radical Addition Polymerization
Decomposition of peroxide I [[right arrow].
It was also observed that the heating of MAF in THF at 70 [degrees] C does not induce addition polymerization
Polystyrene is a thermoplastic formed by addition polymerization
of the monomer vinylbenzene, a.
These may be illustrated with the examples of ethylene for the addition polymerization and that of a diamine-diacid system for the condensation polymerization.
The addition polymerization identifies three major sequences that lead to the end polymer.
The resins' thermal stability in air at 400 F is said to be much better than BMIs, and they cure by addition polymerization
without liberating volatiles.
Polyether polyols are produced by anionic ring opening addition polymerization
of ethylene oxide or propylene oxide.
It was concluded that the polymerization of BMI/ BTA was primarily controlled by both the free radical and Michael addition polymerization mechanisms.
Recently, we have developed a mechanistic model that adequately predicted the Michael addition polymerization of BMI with BTA in the temperature range 383-423 K with the aid of adding sufficient HQ to completely suppress the free radical polymerization (5), This approach is capable of decoupling the rather complicated competitive Michael addition reaction and free radical polymerization mechanisms, thereby leading to the true key kinetic parameters such as the reaction rate constants and activation energy for the Michael addition reaction polymerization.
The material presents both conceptual information as well as specific information for engineers and researchers, and covers such topics as theoretical considerations for self healing materials and concept modeling, extrinsic self-healing via addition polymerization
, anionic polymerization, and intrinsic self-healing using the Diels-Alser Reaction.
Biesenberger and Tadmor investigated addition polymerization
without termination in continuous vessels and compared the obtained molecular weight distribution to that from a batch reactor (9).
