Processability and rheological behaviour, two key parameters in polymer processing, have been investigated. The first material function generated by data of a capillary rheometer for miscible two component polymer mixtures of PVC and atac-PMMA, shows monotonic shear thinning behaviour, which is enhanced by the temperature increasing. No phase separation occurrs when these blends are subjected to different shear conditions. Processability tests performed in a Brabender rheometer, indicated that the presense of PMMA in blends has a significant influence on the fusion characteristics. Fusion time dropps for three times, while plasticating energy decreases for almost 40% (compared to those of pure PVC). Also, the effect of various lubricants has been examined. Some changes have been noticed, but not to such extent as PMMA caused.
