“…It is well known that the reaction of epoxy resin with diamine is a three‐dimensional polymerization. The increment of molecular weight in three‐dimensional directions shows that this polymerization is not limited to chemical crosslinking and that the relationship between initial oligmer and resulting polymer structure and properties is not so straightforward as it might appear 13. In many instances,14, 15 this process is accompanied by physical and structural changes such as micro‐phase separation, vitrification of the reaction medium, as well as heterogeneous polymer network formation.…”

ABSTRACT:The isothermal and nonisothermal cure behaviors of a novel nitrogen-containing epoxy resin (XT resin) were studied by differential scanning calorimetry (DSC). Various kinetic parameters and details of cure process were obtained based on the Avrami theory. The results indicated that Avrami method is suitable for calculating the kinetic parameters up to the gel point at least. The apparent activation energy (E a ) for isothermal cure process was in agreement with that for nonisothermal cure process. E a value in the early stage (78.5-81.0 KJ mol Ϫ1 ) was about three times than that in the later stage (23.3-26.5 KJ mol Ϫ1 ). The kinetic results from Avrami theory may present a combined effect of all factors, and which is helpful to understand the cure technique for XT-DDS system.

New metal phthalocyanine imide copolymers with high thermal stability, based on the reaction between metal (11) 4,4′,4″,4‴‐phthalocyaninetetraamine, 4‐aminophenylether, and 1,2,4,5‐benzenetetracarboxylic dianhydride, were prepared. Infrared (IR) spectra, thermogravimetric analysis (TGA), and viscosity measurements were used to characterize these polymers. All polymers exhibited good thermal and thermooxidative stability at polymer decomposition temperatures (PDT) greater than 500°C in air and nitrogen atmosphere. Another attractive feature is their high char yields—60–75% at 800°C in nitrogen atmosphere. The ratio of the polymer decomposition temperatures in air and nitrogen atmospheres, (PDTair)/(PDT N 2), varied from 0.94 to 0.98. These polymers have promising applications in heat‐stable films, fibers, and coatings.

In this article common synthetic routes toward telechelics, which are polymers with well‐defined functional end groups, are described. Telechelic polymers are available via radical, cationic, and anionic polymerization including reversible addition–fragmentation chain transfer polymerization, atom transfer radical polymerization, and nitroxide mediated polymerization. Furthermore, metathesis has become a valuable tool for the preparation of telechelics. Last but not least selected examples are presented in which step‐growth polymerization has been successfully applied for the synthesis of such well‐defined macromolecules. In specific cases chain scission can also be a useful route.
