“…Research on fluorescent material has attracted great attentions due to wide range of applications such as clean energy technologies [5], explosive sensing, pH/temperature sensor, biological imaging [6], life science, material science, ultrasensitive molecular diagnosis and novel light-emitting nano devices [7], and biological detection schemes, smart polymer machines, fluorescent chemo sensor, fluorescent molecular thermometers, fluorescent imaging, drug delivery carriers, and so on [8,9]. Different methods have been used developed to synthesize fluorescent polymers by many research groups, with new architecture which contain various amounts of fluorophores and show bright fluorescence are synthesized for various applications [10,11].Research on fluorophore-enriched polymers has become an interesting field because of their multipurpose applications as luminescent probes in various areas [12][13][14][15]. In general, there are two ways to synthesize such fluorophore-enriched polymers.…”

Abstract. Numerous polyesters containing heterocyclic ring have been synthesized by the polycondensation method. Ten Polyesters were synthesised having different aliphatic-aromatic diols in the chain having s-triazine ring as main moiety. The polyesters were synthesized by polycondensation of 6-(N-Piperidinyl)-2,4-bis-(7-Hydroxy-Coumarin-3-carbonyl Chloride)-1,3,5-triazine [PCTC] with aliphatic and aromatic diols. Dark brown, light brown, golden and maroon colour showed by novel synthesized polyesters. The solubility of synthesized polyesters was observed in different solvents. The viscosity was studied for all the polyesters. This polyester showed inherent viscosity ranging from 0.402-0.709 dlg -1 in DMF at 25 o C. The synthesized polyesters were characterized by 1 H-NMR, FT-IR, fluorescence spectra. Fluorescent polymers are macromolecules with enormous important applications. The measured data indicates the synthesized aliphatic-aromatic fluorescent polyesters, focussing on synthetic methods, properties and applications. Due to their unique mechanical property and workability, their emerging applications involve the fields of fluorescent probe, smart polymer machines, chemo sensors, biological imaging, P H /temperature sensor, drug delivery and in many fields. Moreover high quality fluorescent polymers give widespread application in advanced bio imaging, ultrasensitive molecular diagnosis, and novel light emitting nano devices.

“…Pummerer used Lewis Acid in these studies. The acylation reactions of PS with organic anhydrides are very important for the synthesis of polyfunctional PS (Kurbanova et al, 2000;Wang et al, 2002). The reactions of anhydrides with commercial polymers were investigated extensively such as polyethylene (Gaylord and Mishra, 1983), polypropylene (Mitsuaki and Masuasu, 1967), polystyrene (PS) (Okudan, 1998;Li et al, 2002;Zheng et al, 2007;Chen et al, 2008) in the presence of catalysts.…”

Polystyrene (PS) has been chemically modified with cyclic anhydrides such as glutaric anhydride (GA), citraconic anhydride (CA) and phthalic anhydride (PA) in the presence of BF 3 .O(C 2 H 5 ) 2 in chloroform and succinic anhydride (SA) in 1,2-dichloroethane. Some important reaction parameters were determined in order to optimize the acylation process. ATR FT- IR and 1 H NMR studies indicate that the acylation reaction can introduce both carboxyl group and double bond (for only citraconic anhydride) onto pendant aromatic groups of the polymer. The adhesion properties and corrosion resistance of the acylated PS on metal surface under various conditions have been investigated.

“…2 The PSMA copolymers for these applications tend to be low in molecular weight. As part of higher molecular weight PS, MA has been incorporated as side chains via acylation 3 and grafting reactions. 4 In our laboratory, divinylbenzene-crosslinked PSMA was synthesized with dicarboxylic acid and dihydroxyphosphino functionalities to allow complexation with divalent metal ions, such as, Pb 2þ , Cu 2þ , Cr 3þ , and Ni 2þ .…”

Polystyrene/maleic anhydride (PSMA) was synthesized to reach a viscosity-average molecular weight of 700 kDa and fabricated into ultrafine fibrous membranes consisting of fibers with an average diameter of 300 nm. These ultrafine PSMA fibers were rendered insoluble in organic solvents by reactions with hydrazine and ethylenediamine (ED). The highly efficient incorporation of diamines into the fibrous membranes was easily achieved by brief immersions in either dilute (0.5 wt %) hydrazine for 1 min or ED ether solution for 2 min. Heating at 150 C for 5 min produced crosslinked PSMA with very little or no solubility in acetone with the retention of the fibrous membrane structure. The ED-crosslinked membranes were particularly stable to both bases and acids as well as hydrophilic solvents, had a 46 water contact angle, and absorbed 22 times the amount of water as the as-spun fibrous membrane. This postfiber-formation crosslinking approach was robust, highly efficient, and fast and required very little crosslinking reagent.
