測定了不同苯二酸二丁酯含量的聚甲基丙烯酸甲酯的軟化温度、二級轉變温度和低温彈性模數,得出苯二酸二丁酯含量和軟化温度的關係式:T=112-947N.並從低温彈性模數說明添加苯二酸二丁酯後改進了聚甲基丙烯酸甲酯的低温度衝擊強度.

The softening point and Young's modulus of polymethylmethacrylate at low temperature with various contents of dibutyl phthalate have been measured by using a Höpier consistometer and a dilatometer respectively, The relationship between the molar concentration of dibutyl phthalate, N, and the softening point, T, can be expressed by the equation T=112-947N.An explanation for the difference between the coeficient 947 and the value 228-232, previously obtained by Zhurkov, is suggested.
