摘　　要：以重质松节油（主要成分长叶烯和口-石竹烯）和马来酸酐为原料，过氧化二叔丁基为引发剂，环己酮为溶剂，合成了重质松节油-马来酸酐共聚物（HTPMA）。通过气相色谱对由重质松节油与马来酸酐本体自由基聚合所得滤液进行分析，可知口-石竹烯与马来酸酐的反应活性比长叶烯高。通过红外光谱，凝胶色谱，元素分析和热重分析对HTPMA的结构和性能进行了表征。采用2-羟基乙基丙烯酸酯对HTPMA进行改性，得到可uv固化的端乙烯基聚酯（HTMHA）。红外光谱分析表明HTPMA的酸酐基团打开，成功引入了端乙烯基团。对HTMHA紫外光固化膜的性能进行了测试，结果表明固化膜具有较好的柔韧性和耐化学品性。The heavy turpentine-maleic anhydride copolymer（HTPMA）was synthesized using heavy turpentine （main components of longifolene and fl-earyophyllene）and maleie anhydride as starting materials, di-tert-butyl peroxide as initiator and eyclohexanone as solvent. The results of gas chromatography analysis of filtrate obtained from the bulk polymerization of heavy turpentine and maleic anhydride showed that the reactivity of fl-caryophyllene and maleic anhydride was better than that of longifolene and maleic anhydride. The structure and properties of HTPMA were characterized by FI＇-IR, GPC, elemental analysis and TG analysis. The HTPMA was further modified by 2-Hydroxyethyl acrylate and the polyester containing terminal vinyl group （HTMHA）was obtained. The FT-IR spectra showed that the anhydride groups of HTPMA were opened, and the terminal vinyl groups were successfully introduced. The performance of HTMHA UV curing film was tested. The results showed that the cured film had good flexibility and chemical resistance.
