Abstract
Reactive gases (NO, SF4 and NH3) as well as volatile compounds (CH3COC l and CH3OH) have been used to modify polymers containing polar functi onal groups. Ethylene-vinyl alcohol, and olefin-acrylic acid copolymer s, have been converted into corresponding nitrites and acetates, acid fluorides, ammonium carboxylates and amides, respectively. The efficie ncy of the reaction was checked by transmission and reflection IR spec troscopy. Significant changes of both gas permeability and surface ten sion were also pointed out.
