Patent abstract
The present invention is generally directed to a method for measuring interfacial stick-slip transitions (SST) and an improved constant-force shear capable of measuring interfacial SST. Some embodiments are capable of measuring SST under simple shear conditions and/or in highly entangled polymer melts. Some embodiments include the application of a constant shearing force to a polymer sample.
