为配合氯化聚丙烯-马来酸酐接枝共聚物(CPP-g-MAH)作为聚烯烃涂料配套底漆的研究,对CPP-g-MAH甲苯溶液的表面张力与浓度和接枝率的关系进行了系统研究。研究表明:CPP-g-MAH溶液表面张力与浓度和接枝率关系可拟合为同一族的指数方程,方程的基本形式为:γ=27.37exp(AC2±B C),常数A、B为与接枝率相关联的常数,该方程揭示了CPP-g-MAH溶液表面张力随浓度和接枝率的变化规律,同时发现体系的表面张力都是在最大浓度处发生突跃。
In order to cope with CPP-g-MAH as a primer for polyolefin coatings, the relationship between surface tension and concentration and graft ratio of CPP-g-MAH toluene solution Conducted a systematic study. The results show that the relationship between surface tension and concentration and grafting rate of CPP-g-MAH solution can be fitted to the exponential equation of the same family. The basic form of the equation is: γ = 27.37exp (AC2 ± BC), constants A and B are Grafting ratio. The equation reveals the variation of surface tension with concentration and grafting rate of CPP-g-MAH solution. At the same time, the surface tension of CPP-g-MAH solution shows a sudden jump at the maximum concentration.
