微波辐射下丙烯海松酸烯丙酯的合成、表征及UV固化反应
Microwave Irradiation Synthesis, Characterization and UV-curing Reaction of Allyl Acrylpimarate
摘要
Abstract
A new polymerized monomer with two allyl groups was synthesized by Diels-Alder reaction, which could introduce the characteristic fused ring structure of rosin acids to the polymers. Allyl acrylpimarate was synthesized by using sodium acrylpimaric rosinate and allyl chloride as raw materials with molar ratio of 1:2, 5% cetyltrimethyl ammonium bromide as catalyst, 0. 02%hydroquinol as polymerization inhibitor and N, N-dimethylformamide as solvent under microwave irradiation. Under the reaction conditions of microwave energy 400 W, reaction time 2. 5 h, reaction temperature 50 ℃, the yield of allyl acrylpimarate( AA) was 72. 9%. The structure of the product was characterized by gas chromatography, gas chromatography mass spectrometry, infrared spectrum, and nuclear magnetic resonance spectra. The IR spectra showed that the characteristic absorption peak of C—C on AA addition appeared at 1686 and 1648 cm-1 . The GC content of AA was determined as 98. 6% by gas chromatography. Mass spectrometry and nuclear magnetic resonance spectra were used to verify the correctness of the structure of AA. The UV curing reaction of AA was studied. The results of infrared spectroscopy showed that the polymerization monomer was a free radical polymerization reaction. The surface curing time of AA decreased with the increasing of photo initiator dosage, decreasing of illumination distance and increasing of illumination intesity. TG and DSC analysis results showed that the UV curing product had good thermal stability with the initial decomposition temperature of 292. 9℃ and initial glass transition temperature of 49. 6 ℃.关键词
