| Popis: | The viscosity of dilute chlorinated polypropylene(CPP)-alkyd resin (344# resin)-toluene solutions at different compositions was measured, and the criteria, α, Δk and β, were calculated from the experimental data. The results obtained indicate that the miscibility of the 344# resin-CPP blends can be predicted by the criterion α, and the blends are miscible when the weight percentage of 344# resin in the blend of CPP and 344# resin is less than 50% (w%), and immiscible when greater than 50% (w%), which is completely consistent with the result predicted by Δk and β. The results are proved by the stability of the 344# resin-CPP solutions and the glossiness of their films. Our work also gives a new blend system predicted by the dilute viscometry, which is miscible in some composition ranges and immiscible in other ranges. The experimental results are of significant value in preparing polypropylene coating. |
