In the present study, we report a strategy to prepare rosin-based plasticizers with differently branched chains, which have the same benzene ring and similar alkane structure compared to phthalate plasticizers. Castor oil methyl ester, cardanol, and triethyl citrate were reacted with the chemical structure of rosin-based plasticizers. Rosin-based plasticizers with differently branched chains as alternative plasticizers for preparing phthalate-free flexible poly(vinyl chloride) films. All rosin-based plasticizers exhibited more excellent solvent extraction performance than phthalate plasticizers in four different solvents. The plasticizing efficiency of rosin-based plasticizers containing triethyl citrate groups reached 85.5%. The relationships between plasticizing efficiency, thermal stability, solvent resistance, tensile properties, and relative molecular mass of the branched chains of rosin-based plasticizers were investigated.
在本研究中，我们报告了一种制备具有不同支链的松香基增塑剂的策略，与邻苯二甲酸酯增塑剂相比，它们具有相同的苯环和相似的烷烃结构。蓖麻油甲酯、腰果酚和柠檬酸三乙酯与松香基增塑剂的化学结构发生反应。具有不同支链的松香基增塑剂可作为制备无邻苯二甲酸酯柔性聚氯乙烯薄膜的替代增塑剂。在四种不同溶剂中，所有松香基增塑剂均表现出比邻苯二甲酸酯增塑剂更优异的溶剂萃取性能。含柠檬酸三乙酯基团的松香基增塑剂的增塑效率达到85.5%。研究了松香基增塑剂的增塑效率、热稳定性、耐溶剂性、拉伸性能与支链相对分子质量之间的关系。
