“…A high refractive index (high n ) is an important factor for the practical application of polymers in advanced optoelectronic fabrications. According to the Lorentz − Lorenz equation, several factors such as the molar refraction, molar volume or density affect the refractive index of polymers which is the key feature for optical applications . Thus, the refractive indices of polymers can be increased by the incorporation of substituents with high molar refractions and low free molecular volumes.…”

Two series of isomers containing pyridine and sulfur unit aromatic diamine monomers, 4,4′‐bis(5‐amino‐2‐pyridinylsulfanyl)diphenyl sulfide (2a), 4,4′‐bis(6‐amino‐3‐pyridinylsulfanyl)diphenyl sulfide (2b) and 4,4′‐bis(5‐amino‐6‐methyl‐2‐pyridinylsulfanyl)diphenyl sulfide (2c), 4,4′‐bis(5‐amino‐4‐methyl‐2‐pyridinylsulfanyl)diphenyl sulfide (2d), were designed and synthesized. Aimed at clarifying the structure–property relationships of pyridine‐ and sulfur‐containing high refractive polymers, 2a was polymerized with various dianhydrides to prepare polyimides PI‐1−PI‐7 and 2b, 2c, 2d were reacted with 4,4′‐[p‐thiobis(phenylenesulfanyl)]diphthalic anhydride to prepare polyimides PI‐8−PI‐10. The polyimides showed excellent optical properties with average refractive indices ranging from 1.7006 to 1.7620 and birefringence as low as 0.0056. Meanwhile, comparative studies on their properties including solubility, thermal and mechanical, and optical transparency properties were performed. Some property differences of the isomers caused by the sequence changes were found. © 2017 Society of Chemical Industry

“…Increases in modulus and strength, losses in elongation at break and impact resistance suggest evidence for antiplasticization phenomena under these conditions, contrary to what is seen in the case for a plasticized matrix. Antiplasticization has been studied by a number of researchers [6][7][8][9][10][11][12][13][14][15]. In applications for gas separations, the result of such an occurrence leads to a decrease in permeability with complex effects on selectivity [6].…”

“…The antiplasticization occurs in many different diluent‐polymer systems as, for example, tricresyl phosphate in polysulfone 13,14 ; dibutylphthalate 15,16 , nonlinear optical dyes such as lead tetracumylphenoxy phthalocyanine and p ‐therphenyl in polycarbonate; phenacetin and acetanilide in poly(ethylene terephthalate) 19 ; 4,4′‐(hexafluoroisopropylidene) diphenol, hydroquinone, and 4‐hydroxybenzophenone in poly(amino‐ether) resin 20 ; water in starch 21–23 ; water in poly(ether ether ketone) 24 ; among others. The antiplasticization of poly(vinyl chloride) has been extensively studied for several diluents.…”

“…This unexpected behavior is known as the antiplasticization effect [6][7][8][9][10] for which the magnitude depends on the molecular characteristics of the additives (size, shape, and stiffness), of the polymers (polarity and stiffness) and of the polymer-additives interactions. 11,12 The antiplasticization occurs in many different diluent-polymer systems as, for example, tricresyl phosphate in polysulfone 13,14 ; dibutylphthalate 15,16 , nonlinear optical dyes such as lead tetracumylphenoxy phthalocyanine 17 and p-therphenyl 18 in polycarbonate; phenacetin and acetanilide in poly(ethylene terephthalate) 19 ; 4,4 0 -(hexafluoroisopropylidene) diphenol, hydroquinone, and 4-hydroxybenzophenone in poly(amino-ether) resin 20 ; water in starch [21][22][23] ; water in poly(ether ether ketone) 24 ; among others.

This article describes the antiplasticization of a commercial polyetherimide ULTEMV R series 1000 [poly(bisphenol A-co-4-nitrophthalic anhydride-co-1,3-phenylenediamine) by resorcinol bis(diphenyl phosphate)] (RDP) and its implications on the thermomechanical processing, namely extrusion and injection molding, as well as on the thermal and mechanical properties of the formulations. This antiplasticization effect allows the processing of polyetherimide formulations at lower temperatures in comparison with neat polymer due to the progressive decrease of the glass transition temperature with increased RDP concentration, as observed by differential scanning calorimetry and dynamic mechanical analysis. The decrease of T g occurs concomitantly with the overlap of the glass transition and b relaxation and with the shift of the c relaxation to higher temperatures. These changes in the relaxation spectrum of polyetherimide formulations are possibly responsible for the increase of the tensile strength and Young's modulus and changes in the fracture mechanism, as observed by stress-strain tests and by scanning electron microscopy, respectively.
