Vapor permeabilities by dynamic sorption

摘要

AbstractA new method of measuring the permeability of plastic films to vapors is described. The method is simple and convenient, uses general‐purpose equipment, and gives good results in a short time. It is easily adapted to vapors other than water vapor. This method is recommended for measurements of permeability where the expense of specialized equipment is not justified. Further studies on effects of parameters such as temperature, humidity, solvation of polymer, etc., are under wa
