An ethylene/vinyl alcohol co-polymer (EVOH) has been chemically modified to induce the formation of ionic clusters. -COOH containing pendant groups have been grafted on the polymer backbone and subsequently have been partially or totally salified. The structure of this class of polymers is expected
In this article, the synthesis and properties of the (ethylene-vinyl acetatevinyl alcohol) terpolymer are studied in detail. A transesterification reaction with alcohols was conducted on poly(ethylene-vinyl acetate) to obtain terpolymers with varying hydroxide contents through three different routes
Coupled measurements of birefringence and IR dichroism of drawn films of vinyl alcohol-ethylene copolymers have led to a value of around 46Π for the angle a between the dipole moment vector of the IR band at 610 cm 01 and the chain axis. The increase of the second moment of the orientation function
