    • The present invention provides a phthalate-free plasticizer for polymer resins. The phthalate-free plasticizer according to the invention includes a mixture of different triesters of glycerin, at least one of which meets the formula: CH2(OOR1)CH(OOR2)CH2(OOR3) wherein at least two of R1, R2, and R3 are different alkyl or aryl groups. Phthalate-free plasticizers according to the invention can be made by esterifyng glycerin with a mixture of acids in the presence of a catalyst. Preferably, the mixture of acids includes at least two selected from the group consisting of alkyl acids and aryl acids, with each acid in the mixture containing up to about 11 carbon atoms, and more preferably from about 4 to about 9 carbon atoms each. The plasticizer according to the invention can be used to modify the properties of a wide variety of polymers including vinyl polymers, rubbers, polyurethanes, and acrylics, and has superb thermostability and low volatility.
    • 本发明提供了一种用于聚合物树脂的不含邻苯二甲酸酯的增塑剂。 根据本发明的不含邻苯二甲酸酯的增塑剂包括甘油的不同三酯的混合物,其中至少一种满足式:CH 2(OOR 1)CH(OOR 2)CH 2(OOR 3),其中R 1,R 2和R 3中的至少两个 是不同的烷基或芳基。 根据本发明的无邻苯二甲酸酯增塑剂可以通过在催化剂存在下用酸的混合物酯化甘油来制备。 优选地,酸的混合物包括选自烷基酸和芳基酸中的至少两种,混合物中的每种酸各含有约11个碳原子,更优选约4至约9个碳原子。 根据本发明的增塑剂可用于改变包括乙烯基聚合物,橡胶,聚氨酯和丙烯酸类的各种聚合物的性质,并且具有极好的热稳定性和低挥发性。
