Ionic polyurethane ( PU ) membranes of hydroxyl-terminated polybutadiene ( HTPB ) and 4,4 -dicyclohexylmethane diisocyanate ( H 12 MDI ) were polymerized by a two-stage method. The ionic group was introduced by adding N-methyldiethanolamine ( MDEA ) as the chain extender of which the tertiary amines
## Abstract The effect of polymer density on the gas permeability of polyethylene film has been studied. The experimental data for permeability __P__ are described by the equation __P__ = __K__(1 โ __d__)__^n^__, where __K__ is a constant characteristic of each gas and __d__ is the sample density.
