Abstract
Phase diagrams of four binary blends of polyisobutylene (component 1) and deuterated polybutadiene (component 2) were determined using small-angle neutron scattering (SANS). Our study covers N1/N2 values ranging from 0.23 to 0.92 and Ni ranging from about 800 to 3600 (Ni is the number of monomers per chain of component i based on a reference volume = 0.1 nm3). The experimentally determined binodal curves were in good agreement with the predictions based on the Flory−Huggins theory using a previously determined composition- and chain-length-dependent Flory−Huggins interaction parameter presented in Nedomaet al.Macromolecules 2008, 41, 5773−5779. The experimentally determined spinodal curves, which were surprisingly close to the experimental binodal curves, deviated significantly from predictions, an observation for which we offer no quantitative explanation.
