Synthesis of solid epoxy resins base on BPCII and bisphenol A using conventional heating equipment and microwave
New solid state epoxy resins based on diglycidyl ether of 1,1-dichloro-2,2 bis (4-hydroxyphenyl), ethylene (BPC) and BPA epoxy resins in the reaction with BPC and BPA were developed. Solid epoxy resins were synthesised by the use of two different heating methods: conventional and microwave reactor. The use of microwave radiation as novel heating medium as an alternative to the conventional methods, which provide a quicker and more effective synthesis. The solid epoxies have high melting points higher than 100 degrees C and the polycondensation degree remains between n = 4-12. Epoxy value stays low and Occurs around 0,02-0,1. BPA epoxy resins and diglycidylether of BPC 11 were compared in terms of reaction speed. It can be seen that the reaction of BPC diglycidylether occurs approximately 20% quicker given the same reaction conditions of temperature, and balance of catalyst. (c) 2006 Wiley Periodicals, Inc.
