Structure studies were performed on PVA gels in mixtures of dimethyl sulfoxide (DMSO) and water using various scattering methods to see the hierarchic structure. It was found that the crosslinking ...

PE/EVOH multilayer films offer improved helium barrier performance and mechanical strength, making them promising materials for pressurized stratospheric balloon applications.

Esters are usually synthesized from an alcohol and an acid; but in the case of vinyl acetate, the starting alcohol would be vinyl alcohol, which is not stable. ... Empirical formula: C 4 H 6 O 2: ...

Even so, some early preparations used acetaldehyde, the aldehyde that corresponds to vinyl alcohol. In a 1958 patent to Celanese (New York City), inventor Arthur W. Schnizer reported the reaction of ...
