## Abstract The effect of a mixed solvent consisting of water and organic solvents such as acetone and methanol on the photografting (Ξ» > 300 nm) of glycidyl methacrylate (GMA) on linear lowβdensity polyethylene film (thickness = 30 ΞΌm) was investigated at 60Β°C. Xanthone was used as a photoinitiato
The macroscopic volume shrinkage and swelling of poly (N-isopropylacrylamide) (PNIPA) gel induced by the compositional change in the methanol-water mixed solvent is correlated to the change in the nanoscopic free volume size and numerical concentration formed in the PNIPA gels. The free volume size
