Polyurethane–attapulgite porous material: Preparation, characterization, and application for dye adsorption
18-12-2012 | Ke Dong, Fengxian Qiu, Xiaorui Guo, Jicheng Xu, Dongya Yang, Kaichen He, Journal of Applied Polymer Science, 2012
Abstract A series of polyurethane–attapulgite porous (HATT/PU) materials were prepared from polyether polyol (NJ‐330), toluene diisocyanate (TDI), acid activated attapulgite (HATT), sodium bicarbonate as foaming agent, dibutylbis (lauroyloxy) tin (DBLT) as catalyst and silicon oil as ...
Fluorescent polymer with CdTe quantum dots and 1,8‐naphthahmide fluorescent polymer: Synthesis, characterization, and FRET
27-11-2012 | Weiyun Huang, Lichao Li, Guodong Hui, Deben Chen, Anyong Zhong, Journal of Applied Polymer Science, 2012
Abstract In this paper, we reported a new method to fabricate CdTe quantum dots (CdTe QDs), which were synthesized in aqueous solution using thioglycolic acid and L‐phenylalanine (L‐Phe) as costabilizing agent. Then, they were transferred into organic phase with the assistance of ...
High performance moisture cured poly(ether–urethane) amide coatings based on renewable resource (cottonseed oil)
23-10-2012 | Pawan D. Meshram, Ravindra G. Puri, Amol L. Patil, Vikas V. Gite, Journal of Coatings Technology and Research, 2012
In this investigation, polyetheramide resin was prepared through the condensation polymerization of N,N-bis (2-hydroxyethyl) cottonseed oil fatty amide (HECOFA) with bisphenol-A. It was further modified by 2,4-toluene diisocyanate (TDI) in 10–30 wt% of polyetheramide to develop a series of ...
Total replacement of solvent in polyurethane synthesis using carbon dioxide soluble 1,3‐dichlorodistannoxane catalysts
27-09-2012 | Yashraj Gartia, Josh Moore, Charlette Felton, Sharon Pulla, Brian Berry, Pradip Munshi, Anindya Ghosh, Journal of Applied Polymer Science, 2012
Abstract This work demonstrates catalytic synthesis of polyurethanes using 1,3‐dichlorodistannoxane catalysts (1) in carbon dioxide (CO2) and carbon dioxide expanded liquids (CXL). Catalytic polyurethane synthesis was also performed in pure organic solvent (dimethylformamide) for ...
Biodegradable solvent-induced shape-memory hyperbranched polyurethane
20-09-2012 | Hemjyoti Kalita, Manabendra Mandal, Niranjan Karak, Journal of Polymer Research, 2012
Solvent-induced shape-memory polymers are of immense interest in various fields, especially biomedicine, as the high transition temperatures required to induce shape recovery in thermoresponsive shape-memory polymers can have adverse effects. In this work, hyperbranched polyurethane was ...
Modification of an urethane polymer by introducing terminal trimethoxysilyl groups and effect of fullerene black on the mechanical properties
14-08-2012 | A. V. Kalinin, A. S. Gavrilov, Russian Journal of Applied Chemistry, 2012
A polyether oligomer with terminal hydroxy groups was modified in succession with 2,4-toluene diisocyanate, allyl alcohol, and trimethoxysilane (hydrosilation). The modified oligomer was vulcanized by the method used for vulcanization of organosilicon elastomers. The effect of additions of ...
Preparation and properties of novel poly(propylene oxide)‐block‐polylactide‐based polyurethane foams
20-07-2012 | Yan Ma, Dongmei Yang, Wenpeng Shi, Suming Li, Zhongyong Fan, Jianjun Tu, Wei Wang, Polymer Engineering and Science, 2012
Abstract A novel degradable flexible polyurethane (PU) foam was prepared by varying the ratio of poly(propylene oxide) (PPO) and triarm poly(propylene oxide)‐block‐polylactide copolymer (PPO‐b‐PLA), and was compared with conventional PU foams based on toluene diisocyanate (TDI) and PPO. ...
Preparation and Characterization of Sustainable Polyurethane Foams from Soybean Oils
16-07-2012 | Ruijun Gu, Samir Konar, Mohini Sain, Journal of the American Oil Chemists' Society, 2012
Polyol derived from soybean oil was made from crude soybean oil by epoxidization and hydroxylation. Soy-based polyurethane (PU) foams were prepared by the in-situ reaction of methylene diphenyl diisocyanate (MDI) polyurea prepolymer and soy-based polyol. A free-rise method was developed to ...
Effects of vinyl isocyanate coupling agent on the tensile properties of Kraft fiber‐unsaturated polyester composites
13-07-2012 | Zhenhua Gao, Dieying Ma, Xinying Lv, Yanhua Zhang, Journal of Applied Polymer Science, 2012
Abstract A vinyl isocyanate (VI) synthesized from toluene diisocyanate and 2‐hydroxyethyl methacrylate was used as a novel coupling agent to obtain strong chemical interfacial adhesion and therefore, improve the tensile properties of Kraft fiber‐reinforced unsaturated polyester (UPE) ...
Thermal stability of polyurethane materials based on castor oil as polyol component
26-06-2012 | Ivan S. Ristić, Zoran D. Bjelović, Berta Holló, Katalin Mészáros Szécsényi, Jaroslava Budinski-Simendić, Nada Lazić, ..., Journal of Thermal Analysis and Calorimetry, 2012
Preparation of the series of polyurethane elastomers and its nanocomposites from castor oil (a vegetable triglyceride) and different isocyanates (aromatic: toluene diisocyanate, TDI and aliphatic: isophorone diisocyanate, IPDI) is described. The synthesis was carried out in bulk and without ...
