中文摘要	the permeability coefficients of a series of copolymers of vinylidene chloride (vdc) with methyl acrylate (ma), butyl acrylate (ba) or vinyl chloride (vc) (as comonomer) to oxygen and carbon dioxide have been measured at 1.0 mpa and 30 degrees c, while those to water vapor have been measured at 30 degrees c and 100% relative humidity. all the copolymers are semicrystalline. vdc/ma copolymers have lower melting temperature compared with vdc/ba copolymers, while that melting temperature of vdc/vc copolymer is higher than that of vdc/acrylate copolymers with the same vdc content. the barrier property of the copolymers is predominantly controlled by crystallite, free volume fraction, and cohesive energy. the permeability coefficients of vdc/ma copolymers to oxygen, carbon dioxide, and water vapor were successfully correlated with the ratio of free volume to cohesive energy.
