<p>First and second virgin polymers, not normally miscible when combined in one or more conventional melt-processing means, are combined in a known melt-processing means having mechanical vibration, referred to as a TekFlow(R) "processor" in which the polymers are extensively shear-thinned, substantially disentangled and stress-fatigues. A process in which melts of each virgin polymer are separately modified, mixed and melt-processed in a conventional extruder, is also effective if the melt of one polymer, modified in a processor, is mixed with virgin melt before being modified in another processor. In each embodiment, the resulting blend is unexpectedly found to be a single phase, that is, a miscible blend.</p> |
