“…Resorcinol was also applied as a co‐monomer to control the thermal properties of polyarylates [ 24,25 ] owing to its kinky structure and to improve the weathering parameters of polyarylates and polycarbonates owing to its UV absorptivity. [ 26–28 ] Though resorcinol is an attractive renewable monomer as noted above, there are few reports on the development of semiaromatic polyesters starting from resorcinol. [ 29–31 ] Foti et al.…”

Recently biobased plastics draw attention as eco‐friendly materials, and it is important to study the effects of substituents, which are popularly found in natural products, on the characteristics of the resulted polymers. In this study, twelve resorcinol‐based semiaromatic polyesters are successfully synthesized using four types of resorcinol derivatives (resorcinol, 2‐methylresorcinol, 5‐methylresorcinol, and 2,5‐dimethylresorcinol) and three types of dicarboxylic acids (glutaric acid, adipic acid, and pimelic acid) to investigate the effect of methylation at the 2‐ and 5‐positions in resorcinol. Glass‐transition temperature of the polyesters is located from ‐3.1 to 37.9 °C, and rises with increasing the number of methyl groups in a resorcinol unit. Crystallinity of the polyesters decreases by methylation to a resorcinol unit, except the polyester from 2‐methylresorcinol and pimelic acid. The mechanical properties of the solvent‐cast films for the polyesters are tunable by the site and number of methyl groups in a resorcinol unit. The major thermal degradation of the polyesters is observed above 300 °C, and the minor thermal decomposition appears between 100 and 200 °C for the polyesters without the resorcinol methylated at the 2‐position and pimelic acid unit.

“…Optimized procedures to prepare PCCD polymers with high melting temperatures have been patented by General Electric Company and introduced to the market, in particular in blends with bisphenol A polycarbonate (under the trade name Xylex TM ) . PCCD has also been proposed for powder coating applications , since a high stability to light, heat, and humidity is required, especially for outdoor applications . In this case, carboxylic end‐groups are more favorable with respect to ester end groups for the crosslinking process .…”

Poly(cyclohexane‐1,4‐dimethylene cyclohexane‐1,4‐dicarboxylate) has been prepared by solid‐state polymerization using 1,4‐cyclohexanedicarboxylic acid or its di‐methylester and 1,4‐cyclohexanedimethanol as monomers. The process consists in a first step in which a prepolymer with high crystallinity is prepared by melt polycondensation and then submitted to solid‐state polymerization (SSP) at a temperature below the melting temperature of the polymer. The use of the solid state process permits to minimize the isomerization from the trans to the cis form in the polymer chain and therefore a polyester with higher crystallinity and melting temperature, compared to those synthesized by the traditional polycondensation routes, can be obtained. For this reason, the SSP process allows to obtain materials with thermo‐mechanical properties that cannot be achieved using the standard polycondensation method. Moreover, the process does not involve a complex multi‐step temperature ramp as in the case of the polycondensation process. POLYM. ENG.
