“…The P3 values on comparison with P2 values give an idea about the length of polymer chain formed during the block copolymerization. The high molecular weight polymer (15,745 g/mol formed in P2 involved in the ROP of CL units and led to the formation of P3 . In the present investigation, we found two chromatographic peaks during the formation of P2 and P3 .…”

“…Various chelating initiators are being used for the ring opening polymerization of CL . Recently, various fluorescence probes initiated ring opening polymerization of CL and reports are available in the literature . By thorough literature survey, we could not find any report based on the poly(sulfanilic acid) (PSA)‐initiated ring opening polymerization of CL.…”

“…Figure c confirms the broken stone‐like surface morphology of P3 with the dispersion of nanospheres with nanovoids. The appearance of broken stone‐like morphology confirmed the presence of PCL segments present in P3 . While comparing the FESEM image of P1 , P2 , and P3 , one can conclude that during the block copolymerization, nanoparticles with the nanovoids are formed which have more biomedical value during an efficient drug delivery process.…”

“…The RB flask was removed from the oil bath and cooled to room temperature. The cooled polymer was dissolved in a CHCl 3 solvent and reprecipitated by the addition of excess of diethyl ether . Here, the diethylether acted as a nonsolvent, i.e to precipitate the diblock copolymer dissolved in CHCl 3 .…”

A triblock copolymer consists of sulfanilic acid, tetrahydrofuran and ε-caprolactone was synthesized and characterized by various analytical techniques such as Fourier transform Infrared spectroscopy, UV-vis spectroscopy, fluorescence spectroscopy, thermogravimetric analysis, differential scanning calorimetry, field emission scanning electron microscopy, gel permeation chromatography and conductivity measurements. The percent relative humidity (RH) of poly(sulfanilic acid) (PSA; P1), poly(sulfanilic acid)-g-poly(tetrahydrofuran) (PSA-g-PTHF; P2), and poly(caprolactone)-block-poly(sulfanlic acid)-g-poly (tetrahydrofuran)-block-poly(ε-caprolactone) (PCL-b-PSA-g-PTHF-b-PCL; P3) were tested at different temperatures. This study infers that the cationically charged polymers exhibited excellent percent RH. C 2015 Wiley Periodicals, Inc. Adv Polym Technol 2016; View this article online at wileyonlinelibrary.com.

Fluorescent and magnetic poly(styrene) (PS) based random co-polymer nanofiber was synthesized in a controlled manner via chemical polymerization in three steps. A fluorescent and magnetic nanohybrid {Fe 3 O 4 /Congored (CR)} was separately prepared and chemically grafted onto the epichlorohydrin (ECH) units of the random co-polymer. Characterizations of the above synthesized polymers were done with the help of Fourier transform infrared (FTIR) spectroscopy, UV-visible spectroscopy, nuclear magnetic resonance (NMR) spectroscopy, fluorescence emission spectroscopy, field emission scanning electron microscopy (FESEM), scanning electron microscopy (SEM), vibrating sample magnetometer (VSM) measurement, differential scanning calorimetry (DSC), thermogravimetric analysis (TGA), and gel permeation chromatography (GPC) like analytical techniques. The FESEM results indicated that after the grafting of nanohybrid onto the random co-polymer backbone, the polymer exhibited a nanofiber like morphology. Due to the surface functionalization and encapsulation reactions, the magnetic moment value of the nanohybrid and its nanocomposites were found to be reduced. Synthesis and characterization of magnetic and fluorescent random co-polymer based nanofiber is the primary target of the present investigation and its application is extended to the catalysis field.
