摘　　要：本文研究了部份醇解PVAc—CH_3OH溶液的流变性能,分别讨论了醇解度(0～46％)以及H_3BO_3(0～1.5％),Cu(No_3)_2(0～5％)对溶液流变性能的影响。实验证明,PVAc—B^(3+)—Cu^2CH_3OH溶液具有稳定的流变性能,可获得良好的可纺性。The rheological properties of partially alcoholized PVAC-CH_3OH soluttion have been studied. The effects of degree of alcoholization, addition of H_3BO_3 (0-1.5％) and Cu (NO_3)_2 (0-5％) on the rheological properties of the solution were discussed respectively. The results show that the PVAC-B^(3+)-Cu^(2+)-CH_3OH solutiou has steady rheological properties and therefore the spinnability of the solution would be fine.
