The phase behaviour of blends of a liquid-crystalline polymer (LCP) and poly(methyl methacrylate) (PMMA), as well as the phase state of blends of PMMA and poly(vinyl acetate) (PVA) has been investigated using light scattering and phase-contrast optical microscopy. The blends of LCP and PMMA have bee

## Abstract Binary blends of the conjugated polymer poly(9,9โdioctylfluorene) (PFO) and the insulating polymer poly(methyl methacrylate) (PMMA) phaseโseparated and exhibited optical and electrical activity in lightโemittingโdiodes. The phaseโseparated PFO columns were uniformly packed and situated
Polymer blends composed of poly ( methyl methacrylate ) ( PMMA ) and poly ( vinyl acetate ) ( PVAc ) were prepared via radical-initiated polymerization of methyl methacrylate ( MMA ) in the presence of PVAc. Differential scanning calorimetry and dynamic mechanical analysis were employed to investiga
