Plasticized compositions exhibiting enhanced thermal processability are produced by substantially saturating a linear alternating polymer of carbon monoxide and at least one ethylenically unsaturated hydrocarbon with water at the melting point of the plasticized composition.

Polyamide advanced composites are formed by the condensation of diacid halides (or dicarboxylic acids) and diamines in a linear or multidimensional morphology with crosslinkable end caps that provide improved solvent- resistance. The diamines and diacid halides generally include "sulfone" linkages in aryl chains to impart the desired combination of physical properties to the oligomers, prepregs, a...

According to the process of this invention, alcohols are recovered from aqueous acid solution by permeation of the alcohol through a perfluorinated ionomer membrane. An improved process for the manufacture of alcohols by acid absorption of olefins is also disclosed, the improvement residing in the use of a perfluorinated ionomer membrane to selectively permeate alcohols from the concentrated aqueo...
