Parametric study of manufacturing ultrafine polybenzimidazole fibers by electrospinningInternational Journal of Plastics Technology - Tập 16 - Trang 101-116 - 2012
S. Anandhan, K. Ponprapakaran, T. Senthil, Gibin George
Polybenzimidazole (PBI), a high performance polymer, was synthesized from 3,3′-diaminobenzidine (DAB) and isophthalic acid (IPA) through polycondensation. The chemical structure of PBI was confirmed by Fourier transform infrared spectroscopy. Thermal characterization of PBI was done by thermogravimetry and differential scanning calorimetry. PBI nanofibers were fabricated by electrospinning of N, N...... hiện toàn bộ
Interpenetrating polymer networks derived from cardanol based dyes and polyol modified castor oil based polyurethanesInternational Journal of Plastics Technology - Tập 15 - Trang 52-67 - 2011

In view of the fast consumption of the petroleum stock and pressing demand for the use of polymeric materials to keep pace with the rate of growth of the world’s population the syntheses of polymers from agricultural products have achieved tremendous momentum at present all over the world. A number of Interpenetrating Polymer Networks were synthesized from polyol modified castor oil polyurethanes ...... hiện toàn bộ
Efficient utilization of anion exchange composites using silica filler for low temperature alkaline membrane fuel cellsInternational Journal of Plastics Technology - Tập 17 - Trang 35-50 - 2013
Rajangam Vinodh, Dharmalingam Sangeetha
Alkaline membrane fuel cells (AMFCs) are advantageous over polymer electrolyte membrane fuel cells (PEMFCs) in terms of electrode reaction kinetics and electrocatalyst versatility. One of the key materials for this type of fuel cell is anion exchange membrane (AEM). In this paper, we report on the fabrication of novel composite membrane from a quaternized tri-block copolymer and silica filler by s...... hiện toàn bộ
Influence of clarifying agent on the properties of polypropylene copolymer industrially injected cups for Brazilian cream cheeseInternational Journal of Plastics Technology - Tập 23 - Trang 170-176 - 2019
Camila F. Drummond, Mayra Stéphanie P. Damas, Claudia Merlini, Rodrigo Battisti
Aiming to achieve different characteristics with polypropylene copolymer, especially in relation to transparency similar to glass packaging, the effect of the addition of a clarifying agent derived from sorbitol to the polypropylene copolymer was studied. A specific cup shape packaging used for Brazilian cream cheese was applied. The samples were produced with different amounts of clarifying agent...... hiện toàn bộ
Numerical study on increasing PVC suspension polymerization productivity by using PSO optimization algorithmInternational Journal of Plastics Technology - Tập 20 - Trang 219-230 - 2016
Reza Darvishi, Mohsen Nasr Esfahany, Rouhollah Bagheri
Despite the high application of poly (vinyl chloride) (PVC), it is still produced by batch wise rectors via suspension polymerization. Therefore, it is essential to improve the productivity of these processes by decreasing in the time of each batch maintaining desired polymer quality. The industrial batch reactors are restricted by a maximum reactor cooling capacity limiting the extent of rate of ...... hiện toàn bộ
Structural characterization and thermal decomposition of radiation induced grafting of glycidyl methacrylate onto LDPE filmsInternational Journal of Plastics Technology - Tập 19 - Trang 178-190 - 2015
D. M. Alshangiti
The radiation initiated grafting of glycidyl methacrylate (GMA) onto low density polyethylene (LDPE) films has been investigated using a direct radiation technique. The influence of irradiation dose on the grafting yield was investigated. The grafted films were characterized to determine the structural changes with X-ray diffraction and Fourier transform infrared spectroscopy. The optical properti...... hiện toàn bộ
Synthesis and Characterization of polymer resins from renewable resourceInternational Journal of Plastics Technology - Tập 21 - Trang 427-443 - 2017
S. G. Jebastin Andrews, V. Rama, C. V. Mythili
As a alternate to the use of conventional reinforcing synthetic resins, biobased resins were synthesized from renewable resources such as cardanol and furfural. Cardanol is the meta- substituted phenolic compound isolated from cashew nut shell liquid, a byproduct of cashew industry. P-chloroaniline has been diazotised and coupled with cardanol to prepare diazotised p-chloroaniline cardanol dye (bi...... hiện toàn bộ
