The percentage conversion of the reaction was followed by Fourier transform infrared (FTIR) spectroscopy. The specimen temperature during the polymerization process was measured to select a suitable temperature for comparison with the conventional method. The results indicate that a similar comparable temperature of about 52°C was found for all the microwave power settings tested. The microwave polymerization process was compared with that of the thermal method at 52(±1)°C under comparable reaction conditions. The reaction rate enhancement of the microwave polymerization compared to the thermal method was found to be as follows: 275% for the 500 W, 220% for the 300 W, and 138% for the 200 W, indicating a significant correlation between the reaction rate enhancement and the level of microwave power used. © 1997 John Wiley & Sons, Inc.||Source Title:||Journal of Applied Polymer Science||URI:||http://scholarbank.nus.edu.sg/handle/10635/114716||ISSN:||00218995|
