Abstract

Abstract: The polymer of rosin allyl alcohol ester was synthesized by microwave irradiation heating and routine heating method. The structure of the polymer was identified by IR, UV. Softening point and thermogravimetric analysis(TGA) of the polymer were measured and analyzed. Results showed the crosslinked structure of the synthesized polymer through reaction participated by the conjugated double bonds of rosin.Softening point of the polymer was above 300℃. Molecular weight of the polymers by microwave irradiation and routine method were above 29:305 and 3:910, respectively, and that of the polymer by routine method with the addition of crosslinking agent was above 9729. More double bonds were observed to be retained in the latter polymer which has poor thermal stability. Microwave assisted synthesis was a quick and convenient way to synthesize the polymer of rosin allyl alcohol ester, and the performances of the product were superior to those by routine method.

Key words: microwave irradiation heating, polymer of rosin allyl alcohol ester, rosin
