Analysis of polymers using evolved-gas and direct-pyrolysis techniques
(Royal Society of Chemistry, 1994)Thermal analysis of polystyrene, poly(p-methylstyrene) and poly(α-methylstyrene) has been carried out using evolved-gas analysis by infrared and mass spectrometry, and direct-pyrolysis analysis by mass spectrometric ... -
Characterization of degradation products of polyethylene oxide by pyrolysis mass spectrometry
(Pergamon Press, 1994)The techniques of direct and indirect (evolved gas analysis) pyrolysis MS are used to characterize the thermal degradation products of polyethylene oxide. Using direct pyrolysis MS technique the main degradation process ... -
A conducting composite of polythiophene: synthesis and characterization
(John Wiley & Sons Ltd., 1996)Conducting polymer composites of polythiophene, using a polyamide as the insulating matrix, were prepared via electrochemical methods. The characterization of the composite was done by scanning electron microscopy, ... -
Conducting polymer composites of polythiophene with natural and synthetic rubbers
(Elsevier, 1996)Electrochemical synthesis of conducting polymer composites of polythiophene was achieved. Synthetic and natural rubbers were used as the insulating polymer matrices. FT-IR, differential scanning calorimetry (DSC), scanning ... -
Cyclodextrin functionalized poly(methyl methacrylate) (PMMA) electrospun nanofibers for organic vapors waste treatment
(Elsevier BV, 2010)Poly(methyl methacrylate) (PMMA) nanofibers containing the inclusion complex forming betacyclodextrin (_-CD) were successfully produced by means of electrospinning in order to develop functional nanofibrous webs for ... -
Determination of electron affinity of phenyl radical by dissociative electron attachment technique
(John Wiley & Sons, 1993-03) -
Electrospinning of functional poly(methyl methacrylate) nanofibers containing cyclodextrin-menthol inclusion complexes
(Institute of Physics Publishing, 2009)Electrospinning of nanofibers with cyclodextrin inclusion complexes (CD-ICs) is particularly attractive since distinct properties can be obtained by combining the nanofibers with specific functions of the CD-ICs. Here we ... -
Electrospun polyethylene oxide (PEO) nanofibers containing cyclodextrin inclusion complex
(American Scientific Publishers, 2011)In this study, we obtained functional electrospun nanofibers containing stable fragrance/flavor molecule facilitated by cyclodextrin inclusion complexation. Menthol was used as a model fragrance/flavor molecule and we have ... -
Functional electrospun polystyrene nanofibers incorporating α-, β-, and γ-cyclodextrins: Comparison of molecular filter performance
(2010)Electrospinning has been used to successfully create polystyrene (PS) nanofibers containing either of three different types of cyclodextrin (CD); α-CD, β-CD, and γ-CD. These three CDs are chosen because they have different ... -
Investigation of polymerization of benzoxazines and thermal degradation characteristics of polybenzoxazines via direct pyrolysis mass spectrometry
(Wiley, 2012-10)Polymerization of benzoxazines and thermal degradation mechanisms of polybenzoxazines were investigated using the direct pyrolysis mass spectrometry (DP-MS) technique. The benzoxazine structures were based on phenol and ... -
Preparation and characterization of polystyrene-b-poly(2-vinylpyridine) coordinated to metal ion nanoparticles
(Elsevier, 2014-03)In this study, Co, Cr or Au3+ functional polystyrene-block- poly(2-vinylpyridine), PS-b-P2VP complexes were prepared and characterized. Coordination of metal atom or ion to nitrogen atom of pyridine rings was confirmed by ... -
Pyrolysis mass spectrometric analysis of styrene-butadiene block and random copolymers
(Elsevier, 1997-02)Direct pyrolysis mass spectrometric analysis of a styrene-butadiene-styrene block copolymer indicated that thermal decomposition of each block shows a resemblance to the related homopolymer, giving a possibility of ... -
Pyrolysis mass spectrometric analysis of styrene-isoprene-styrene copolymers
(Elsevier, 1999-05)Thermal analysis of styrene±isoprene±styrene block copolymer, using the direct pyrolysis mass spectrometry (MS) technique, indicated that each block showed very similar thermal behavior with the corresponding homopolymer. The ... -
A pyrolysis mass spectrometry study of polythiophene-natural rubber and polythiophene-synthetic rubber conducting polymer composites
(Elsevier, 1997)The thermal behaviors and degradation products of conducting polymer composites prepared by electrooxidation of thiophene using natural rubber or synthetic rubber as the insulating matrix were studied by direct and indirect ... -
Synthesis, characterization and thermal properties of Alkyl-functional naphthoxazines
(Wiley, 2013-02-15)A series of alkyl-functional naphthoxazine resins having various alkyl chain lengths from C1 to C18 are synthesized with a high yield and high purity by the reactions of 1,5-dihydroxynaphthalene, formaldehyde, and aliphatic ...
