Abstract
The influence of two distinct types of water leachable polymeric addit ives upon the transport properties across polymer latex films is consi dered. Hydroxypropyl methylcellulose, added as an aqueous solution, an d a methyl methacrylate-methacrylic acid copolymer, added as latex par ticles, are both shown to be more effective than lower molecular weigh t rapidly water soluble additives, typified by sucrose, in enhancing s olute transport and creating pathways for convective diffusion.
