| 摘 要： | 本文用快速动态渗透压法和恒定外加盐浓度稀释法测定了丙烯酸和丙烯腈共聚物溶液的渗透压和特性粘数,提出在25°.10.02℃下在分别含有0.03N;0.066N,0.13N和0.24N NaNO_3的DMF中,AA-AN的分子量和特性粘度经验表达式为: μ]_(0.03N)=1.390×10~(-3)M~(0.610) μ]_(0.066N)=1.455×10~(-3)M~(0.602) μ]_(0.12N)=2.04×10~(-3)M~(0.557) μ]_(0.24N)=3.077×10~(-3)M~(0.519) 并对盐浓度和温度对第二维里系数的影响进行了讨论。

| Abstract: | The osmotic pressures and intrinsic viscosities of the fractional samples of poly (Acrylic Acid-CO-Acrylonitrile)were determined by rapid dynamic osmometric method and dil ution method under constant concentration of added salt.The equation which relates the intrisic viscosities n] with molecular weight Mn of P(AA-CO-AN)at (25.00.02)1C in DMF containing 0.03N,0.066N,0.12N and 0.24N of NaNO3 was preposeaAlso,the second virial coefficiants varying with salt concentra-tions and temperatures have been discussed |
