Abstract: Improved shaped polymeric articles, including ostomy seals, are obtained by radiation crosslinking an acrylamide polymer composition comprising a water-soluble acrylamide polymer plasticized with a quantity of a water-miscible polyol (containing water) that provides a soft, flexible and elastomeric composition.

Abstract: Disclosed is a process for preparing alkenyl ethers from high molecular weight polyols in a liquid phase system containing concentrated alkali metal hydroxide, water, water immiscible hydrocarbon solvent and high molecular weight polyol such that the addition of an alkenyl halide results in a reaction which yields an alkenyl ether product which is not readily distillable from the reaction solution at slightly elevated temperatures and atmospheric pressures.

Abstract: Disclosed is a polymercaptan material and method for preparation thereof useful in the curing of epoxy resins to impart a more hydrophobic characteristic to the resultant thermoset polymers for use in applications where there is frequent contact with water. The compound described and prepared is a propoxylated ether polythiol of the structure: ##STR1## WHEREIN Y IS AN INTEGER OF AT LEAST 1, X IS AN INTEGER OF AT LEAST 2, R is a polyol consisting of atoms of carbon, hydrogen and oxygen and free of reactive functional groups and the total number carbon atoms in R and ##STR2## IS GREATER THAN 15.
