In this study, a polybenzoxazine, (PPab) based on phenol and 4-aminomethyl benzoate and its composites containing various amounts of 3-hydroxyphenylboronic acid, (HB) were prepared by stepwise curing. It has been found that thermal properties of composites were improved as the amount of HB introduced was increased. The improvements in thermal characteristics were associated with condensation reactions of hydroxyl groups of polybenzoxazine and ester groups on the aniline linkages yielding a highly cross-linked structure. In addition, application of direct pyrolysis mass spectrometry, DP-MS, technique supplied information pointing out generation of a boroxine network by self-condensation reactions of B-OH groups.

The effect of aromatic diboronic acid on characteristics of polybenzoxazine based on phenol and 4-aminomethylbenzoate İPEK, HALİL; Hacaloğlu, Jale (2018-11-23) In this study, a polybenzoxazine, (PPab) based on phenol and 4-aminomethyl benzoate and its composites containing various amounts of 1,4-benzene diboronic acid, (BDBA) were synthesized by stepwise curing. It has been determined that both thermal stability and char yield were increased as the amount of BDBA incorporated was increased. The improvements in thermal characteristics were associated with condensation reactions of B-OH of BDBA and not only with hydroxyl groups of polybenzoxazine but also ester grou...
Effects of aromatic diboronic acid on thermal charateristics of polybenzoxazines based on phenol and aniline Telli, Aysegul Hisar; Hacaloğlu, Jale (2018-11-01) In this work, polybenzoxazines based on phenol and aniline were prepared by curing as-synthesized and purified monomers in the presence of aromatic diboronic acid, BDBA. Condensation reactions between BOH groups of diboronic acid and phenolic OH groups of benzoxazine took place during curing only when unreacted phenol, or low mass oligomers were present in the medium. Generation of fragments involving B-O-C groups and significant improvement in thermal characteristics were detected upon curing the as-synthe...
Synthesis and analysis of thermal characteristics of polybenzoxazine based on phenol and 3-Amino phenyl boronic acid İPEK, HALİL; Hacaloğlu, Jale (2019-07-12) In this work, 3-amino phenyl boronic acid (AB) was used as an aniline derivative in the preparation of polybenzoxazine based on phenol. In order to investigate the effect of boronic acid on thermal characteristics, polybenzoxazines based on pure aniline and 50% aniline and AB mixture were also prepared and analyzed. Significant improvements in thermal characteristics, increase in thermal stability and char yield, was recorded for the polymers based on AB or its mixture. This behavior was associated with cro...
The use of pyrolysis mass spectrometry to investigate polymerization and degradation processes of methyl amine-based benzoxazine Bagherifam, Shahla; Uyar, Tamer; Ishida, Hatsuo; Hacaloğlu, Jale (2010-06-01) In this study, direct pyrolysis mass spectrometry, DP-MS, was applied to investigate curing and polymerization mechanisms of phenol and methyl amine-based benzoxazine monomer, and thermal decomposition and crosslinking characteristics of the corresponding polybenzoxazine. The results indicated opposing polymerization reaction routes besides the generally accepted one. The cleavage of C-O bonds of the oxazine rings either followed by transformation into a polymer constituting ortho or para substituted phenol...
The effect of triethanolamine on thermal decomposition of GAP Fazhoğlu, Hatice; Hacaloğlu, Jale (2002-01-01) The effect of triethanolamine (TEA) on thermal behavior of glycidyl azide polymer (GAP) has been investigated by direct pyrolysis mass spectrometry technique. It has been observed that thermal degradation of GAP-TEA mixture also begins with the cleavage of the side groups as in the case of GAP. Again, the main decomposition started with the elimination of molecular nitrogen from the azide functional group, and a quite similar degradation mechanism has been proposed. The increase in the thermal stability of ...
