Arriola, Modeling of addition polymerization
The addition polymerization
identifies three major sequences that lead to the end polymer.
For a polymer science laboratory course, the ring-opening polymerization of PLA complemented other polymerization methods, Including addition polymerization
, solution polycondensation of linear polyesters, Interfacial polymerization of linear polyesters ("nylon rope trick"), enzymatic polymerization, and emulsion polymerization.
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).
The objective of this work was to focus on the investigation of the kinetics of Michael addition polymerization
of BMI/BTA (2/1 (mol/mol)) in NMP at different temperatures with the aid of adding sufficient HQ to completely suppress the free radical polymerization.
PMKPR was synthesized by addition polymerization
between epoxy and amine group.

of n-Butylacrylate and Hydroxyethyl Methacrylate.
The kinetic scheme for a radical addition polymerization
is given in Table 1.
They are prepared by various routes (1), like polycondensation of diamines-teracarboxylic acid, addition polymerization
of bismaleimides and Diels-Alder (DA) polymerization of bisdiene-bismaleimide (1).
Many addition polymerization
reactions are equilibrium reactions.
The bulk copolymerization of styrene with n-butylmethacrylate is a free radical addition polymerization
. This means that after initiation a polymer chain grows in a rather short time (propagation) because of a termination reaction the polymer chain is excluded from further reaction.
The bulk copolymerization of n-butylmethacrylate (BMA) with 2-hydroxypropylmethacrylate (HPMA), which was carried out in an extruder to investigate the reactive extrusion process, is a free radical addition polymerization
. This implies that the polymer chains are formed in a very short time, after which they are excluded from further reaction.
