“…[5][6][7][8] Nevertheless, these polymers have poor solubility in common organic solvents and have a relatively low glass transition temperature (T g ) at approximately 190 ∘ C, thus posing challenges for their widespread applications. 9,10 Numerous efforts, such as introducing asymmetric units, 11 non-coplanar units 12 and bulky pendent groups [13][14][15] along the polymer backbone, have been made to improve the solubility and enhance the thermal properties of these PARs.…”

A series of copolyarylates (PP0–PP100) containing phthalide groups was synthesized via interfacial polymerization from a mixture of phenolphthalein (PP) and bisphenol A with molar equivalent of terephthalyl chloride. Incorporating PP into the polymer chain improved the solubility of the polyarylates in common organic solvents. The glass transition temperature (191–314 °C), residual weight percentage, Young's modulus (1.7–2.8 GPa), solubility and complex melt viscosity of the copolyarylates increased with increasing PP units in the copolymerization. By contrast, crystallinity and elongation at break (14.1 to 11.2%) of the copolyarylates decreased with increasing PP units in the polymer backbone. When the PP content increased over 30 mol% (PP30), the copolyarylates became amorphous polymers. When the PP content was below 30 mol%, the copolyarylates exhibited good melt processability. With regards to its solubility, thermal stability, mechanical properties and melt processability, PP30 may be considered as a promising candidate in the field of processable high‐performance engineering plastics. © 2019 Society of Chemical Industry

“…All these findings clearly proved the chemical structures of the clickable PPN 3 and FAl prior to the CuAAC click reaction. The peaks at 4.60 and 5.88–6.27 assigned to f and g protons and a new peak at around 8.22 ppm (d) corresponding to triazole ring were great evidences of formation the clicked PPN 3 …”

Synthesis of fluorine containing polypropylene (PP F) from chlorinated polypropylene (PP Cl) via Cu(I) catalyzed Huisgen type 1,3-dipolar cycloaddition (CuAAC) and its water repellency properties are demonstrated. Initially, clickable azido-functional polypropylene (PP N 3 ) and alkyne-functionalized fluorine compound (F Al) are independently prepared by nucleophilic substitution of PP Cl with azidotrimethylsilane-tetrabutylammonium fluoride and esterification reactions of 2,2,3,3,4,4,5,5-octafluoro-1-pentanol with 4-pentyonic acid. The CuAAC reaction between PP N 3 and F Al leads to corresponding PP F under mild conditions. The chemical structures and surface properties of desired PP F are characterized by Fourier transform infrared, 1 H-NMR, differential scanning calorimetry, scanning electron microscopy, atomic force microscope, and contact angle analyses. Based on water contact angle (WCA) measurement, it is found that both PP Cl and PP N 3 films have shown similar hydrophobicity, whereas the WCA of PP F is surprisingly decreased due to the presence of ester and triazole groups coming from F Al compound and the clicked product. This facile modification procedure could be utilized in order to alter the wetting or thermal properties of the commercial polymers for potential applications.
