The adsorption of polyethylene oxide of molecular weight 17 800 and 87 000 at the air/water interface has been studied by neutron reflection and surface tension measurements. Over the concentration range 10−4−10−1 wt% of polymer the surface exc

Surface pressure-area isotherms on poly(methyl methacrylate) ‘monolayers’ spread at the air-water interface show that the isotactic polymer is in good solvent conditions, whereas the atactic and syndiotactic isomers are in thermodynamic environme

The effectiveness of a "solvent annealing" process was investigated for thin (approximately 150 nm) polystyrene films, in which the diffusion and reorganization of polymer chains were mediated by the controlled absorption of cyclohexane vapor. Result

A small-scale flow cell has been developed and used for small-angle neutron scattering (SANS) investigations of polymer melts in Poiseuille flow through a 4:1 contraction. The cell enables the investigation of polymer melt flow subject to a volumetri

A series of fractions of a hyperbranched polyester in deutero tetrahydrofuran solution were investigated by small-angle neutron scattering. Concentrations of polymer from 2 to 5% w/v were used, and the molecular parameters were obtained from Zimm plo

A hyperbranched polyester was fractionated by precipitation to produce 10 fractions with molecular weights between 20 × 103 and 520 × 103 g mol−1. Each of these fractions was examined by size exclusion chromatography, dilute-solution viscometry,

Monte Carlo simulations have been carried out for an off-lattice model of an amphiphilic polymer at a hydrophobic/hydrophilic interface. The model system consists of a polynorbornene backbone with poly(ethylene oxide) (PEO) grafts modelled atomistica
