通常溶度参数是在室温下测定的.由于一般认为温度对溶度参数影响不大,因而对于温度对溶度参数的影响并没有给予足够的重视.使用Funasaka的数据,计算了丙烯-丁烯共聚物由马来酸酐接枝改性后120℃的溶度参数,并和室温下溶度参数作了对比.发现总溶度参数虽然变化不算大,但Hansen球半径和缔合力参数都有增加,因而可溶溶剂数目明显增加,由此认为温度对溶度参数的影响值得人们注意.所用的优化法计算方法,对于计算三维溶度参数也具有一定参考价值.

Usually solubility parameters are determined at room temperature. Since it is generally believed that temperature has little effect on solubility parameters, not enough attention is paid to the influence of temperature on solubility parameters. Using the data of Funasaka, the solubility parameters of propylene-butene copolymer after grafting from maleic anhydride were calculated at 120°C, and the solubility parameters were compared with the solubility parameters at room temperature. It is found that although the total solubility parameters do not change much, the Hansen sphere radius and association force parameters increase, so the number of soluble solvents increases significantly, so it is believed that the influence of temperature on the solubility parameters is worth noting. The optimization method used also has certain reference value for calculating three-dimensional solubility parameters.
