The crystallization and melting of binary mixtures of the polyethylene
- Institute of Molecular Biophysics, Tallahassee, FL (United States)
The crystallization and melting of binary mixtures of linear polyethylene with either random ethylene copolymers (short-chain branched) or long-chain branched polyethylenes, have been investigated. Initially, model systems involving a linear polyethylene, with either hydrogenated poly(butadiene) or a three armed star hydrogenated poly(butadiene) were studied. Each of these components was a molecular weight faction with a narrow composition distribution. Molecular weights were matched for each pair so that the results and interpretations are not encumbered by polydispersity and fractionation effects. Kinetics and fusion subsequent to isothermal crystallization, without cooling, were studied. The necessary conditions of composition and crystallization temperature for the co-crystallization of the two components to occur was established. Based on these studies, polydisperse systems were investigated and the results will be reported.
