APPLICATIONS OF SUCCESSIVE SELF-NUCLEATION AND ANNEALING (SSA) IN POLYOLEFIN BLENDS CHARACTERIZATION

摘要

The technique of Successive Self-Nucleation and Annealing (SSA) has been applied to thermally fractionate two types of ethyiene/α-olefin copolymers and their blends. The results demonstrate the usefulness of SSA to determine the distribution of lamellar thickness and short chain branching (SCB) in the neat polymers and the miscibility of their blends.
