Of work viscometer: Ubbelohde viscometer ( diluted), in line with the GB/ T1632-93 standard.
工作粘度计：乌氏粘度计（稀释型），符合GB/T1632-93标准要求。
The melting point of three block copolymers was measured with microscope as 232, 248 and 260 ℃, respectively. The intrinsic viscosity of the block copolymer with soft-and-hard segment ratio of 7/ 3 was measured as 1.12 dL/ g with a Ubbelohde viscometer.
利用显微熔点仪、乌式粘度计测定了共聚物的熔点和特性粘数，3种共聚物熔点分别为232248260℃，软／硬段比例为7／3的共聚物的特性粘数为1.12dL／g。
Ubbelohde viscometer was used to determine the intrinsic viscosity of the polymer. Through the intrinsic viscosity to compare the molecular of the polymer, study the effect of the polymerization condition to the the molecular of polymer.
用乌氏粘度计测定了四种聚合物的特性粘度，通过特性粘度大小比较聚合物分子量大小，研究了聚合条件对聚合物分子量大小的影响。
The molecule structures were characterized by fourier transform infrared ( FTIR), nuclear magnetic resonance ( 1H-NMR), and intrinsic viscosity were measured by ubbelohde viscometer.
利用傅立叶变换红外（FTIR）、质子核磁共振（1HNMR）进行结构表征，乌氏粘度计测其粘度。
