Abstract

We examine damping and slipping behavior of highly entangled polyisobutylene (PIB). Two types of PIB samples were prepared for comparison: One is PIB melts stuck with the metal plates of rheometer with adhesive, and another is the melts without adhesive. Comparison of the damping and the stress-strain behavior of the two types of samples gives an evidence of slipping for the samples without adhesive. Together with the data for another grade of PIB, it is suggested that a critical value for slipping does not depends on the molecular weight and lies around 0.2 MPa.
