摘要:
采用苯酐吡啶法研究了样品质量与酸酐质量对树脂羟值的影响,获得测试羟值小于100的树脂的最佳条件为:试样的质量应大于3 g,酸酐量应为理论酸酐量的1.8倍左右.采用红外光谱的相对积分面积法分析测试树脂的羟值,以树脂的甲基峰面积为基准,用积分法求得羟基峰的面积S2与甲基峰的面积S1的比值与树脂的羟值存在较好的线性关系.
Abstract:
In this paper, the hydroxyl value of polymers was measured by heating phthalic anhydride via acylation method. To measure hydroxyl value lower than 100 of polymers the best conditions is: the weight of sample should be more than 3g; the weight of phthalic anhydride should be as 1.8 times as theory phthalic anhydride. We study hydroxyl value of polymers using the relative area methodof infrared spectroscopy. Taking the —CH3 peak of polymers as bases, the —CH3 peak area S1 and —OH peak area S2 were integralated by a oringin soft. We found that hydroxyl has a good lineal formula with relative area(RA)S2/S1.
