U-7、U-8黑推光漆GPC法研究

A Study on Black Selfpolish Lacquer U-7 and U-8 by GPC Method

本文用LC6-AGPC仪测定生漆、黑推光漆、U-7A清漆、U-8A清漆、U7-A和U8-A黑推光漆的分子量和分子量分布。根据测定结果,计算漆酚类聚合物的常数K=1.705×10^(-2),α=0.8802。黑推光漆、U7-A清漆、U8-A清漆、U-7黑推光漆和U-8黑推光漆的主要分子量分别为8.80×11~2,2.76×10~3,2.69×10~3,2.94×10~3和2.69×10~3。

Using a LC-6A GPC apparatus, molecular weight and distribution of molecular weight of raul lacquer, black selfpolished lacquer, varnish U-7A, vanish U-8A, black selfpolished lacquers U-7 and U-8 are analyzed. We can calculate the constants K and α of urushiol type polymer, obtain K=1.705×10^(-2), α=0.8802. The main M.W. of black selfpolished lacquers U-7 and U-8 are 8.8×10~2, 2.76×10~3, 2.68×10~3, 2.94×10~2 and 2.69×10~3.
