Preparation of Organic/Inorganic Composite Phenolic Resin and Application in Al2O3‐C Refractories

03.07.2015 | Fucheng Wang, Lei Zhao, Wei Fang, Xuan He, Feng Liang, Hui Chen, Huan Chen, Xing Du, International Journal of Applied Ceramic Technology, 2015

An organic/inorganic composite phenolic resin (CPR) was synthesized via silicon particles insitu composite with water‐soluble lignin–phenolic resin. It was observed that silicon particles were uniformly dispersed in the organic matrix. The oxidation activation energies of the pyrolytic products ...

Synthesis and properties of cross‐linked polymers from epoxidized rubber seed oil and triethylenetetramine

03.07.2015 | Muhammad Yusuf Abduh, Muhammad Iqbal, Francesco Picchioni, Robert Manurung, Hero J. Heeres, Journal of Applied Polymer Science, 2015

ABSTRACT A series of epoxidized oils were prepared from rubber seed, soybean, jatropha, palm, and coconut oils. The epoxy content varied from 0.03 to 7.4 wt %, in accordance with the degree of unsaturation of the oils (lowest for coconut, highest for rubber seed oil). Bulk ...
