Abstract

The temperature dependence of the Flory–Huggins interaction parameter (Formula presented.) for poly(n-butyl acrylate)-b-poly(methyl methacrylate) (PBA-b-PMMA) was quantified from small-angle X-ray scattering (SAXS) analysis using random phase approximation (RPA) theory. It was found from the (Formula presented.) estimation ((Formula presented.)) that the enthalpic contribution, (Formula presented.), a measure for temperature susceptibility of (Formula presented.), is 1.7–4.5 folds smaller for PBA-b-PMMA than for the conventional styrene-diene-based block copolymers, which have been widely used for thermoplastic elastomers. This finding suggests that these fully acrylic components can be a desirable chemical pair for constituting terpolymers applied for thermally stable and mechanically resilient elastomers.
