Equilibrium constants determined from low molecular weight mixtures are used to predict the phase behavior of analogous polymer blends. Due consideration is given to intramolecular screening and functional group accessibility, factors that are a direct consequence of chain connectivity.
Deuterium-labeled polystyrene modified by random distributions of the comonomer p- (1,1,1,3,3,3-hexaflouro-2-hydroxyisopropyl)-โฃ-methyl-styrene [DPS(OH)] has been blended with poly(butyl methacrylate) (PBMA) and studied with small-angle neutron scattering (SANS).

Successive desorption experiments of water vapor in poly(methyl methacrylate) (PMMA) were performed at temperatures from 31.0 to 45.0ยฐC. The solubility of water in PMMA was found to be independent of temperature in agreement with literature findings. But the results for diffusion showed stronger dep
