本文提出用凝胶渗透色谱(GPC)测定聚乙烯酸肉桂酸酯(PC)的分子量和分子量分布。并且,作出了几个国内外PC光致抗蚀剂样品的微分和积分分布曲线。 用国产的GPC仪器,柱的填料是NDG—L多孔硅胶球,用较窄分布的PS标样标定柱子,其分子量范围在1.8×10—3×10~3区间,校正曲线呈线性关系,色谱柱的理论塔板数可达到2000块/米以上。 在这种凝胶中,用PS作为标样,应用流体力
In this paper, the molecular weight and molecular weight distribution of poly (vinylcinnamate) (PC) were determined by gel permeation chromatography (GPC). And, made a few domestic and foreign PC photoresist samples differential and integral distribution curve. Using domestic GPC instrument, the column packing was NDG-L porous silica gel. The column was calibrated with narrower distribution PS standard. The molecular weight of the column was in the range of 1.8 × 10-3 × 10-3. The calibration curve showed a linear relationship. The chromatogram The theoretical number of columns can reach 2000 / m above. In this gel, using PS as a standard, fluid force is applied
