【摘要】 本文运用IR和PGC等方法对P1120涂层胶进行了剖析。比较共聚样品和P1120的氰基相对峰高,测出P1120中AN组份为10.0％; EA/BA共聚比测定;从IR谱图中找到了共混比和酯基骨架振动相对峰高之间的线性关系;然后,对相同系列共混样品进行了PGC测定,建立了共混比和裂解单体及其醇的面积份数之间的线性方程。用IR、PGC测得P1120胶中的EA/BA/AN共聚比分别为51.7/38.3/10.0和50.4/39.6/10.0。更多还原

【Abstract】 In this paper, a solvent based acrylic coating CRISCOAT P1120 was analysed by means of TR, PGC etc. The linear relation between blend ratios of PEA, PBA and relative altitude (1025 cm^-1/ 1065 cm^-1) has been obtained by IR. The same blends of PEA, PBA have been determined by PGC. By the determinations of IR, PGC, the ratios of EA / BA / AN in P1120 has been determined to be 51.8 / 38.3 / 10.0 and 50.4/39.6 / 10.0 respectively.更多还原
