Disclosed are compositions useful as surface coatings for nonwoven substrates which compositions are reaction products of a melamine formaldehyde compound, long chain saturated alcohols and long chain saturated or unsaturated polyethoxylated alcohols. The invention compositions when used to surface size paper impart oil, water and polar solvent resistance thereto. The compositions may be used alone or as substantial replacements for anionic or non-ionic fluorocarbon based surface sizes that are typically used to impart oil resistance to paper.

Surface sizing composition

Discloses a solid polymer electrolyte having ring ethers bonded to a polymer matrix, with metal ions chelated by the ring ethers.

Electro organic method and apparatus for carrying out same

In the preparation of methylchloroform by vapor phase chlorination of 1,1-dichloroethane, the formation of undesirable chlorohydrocarbon reaction products is suppressed by conducting the vapor phase reaction in the presence of a controlled amount of carbon dioxide gas.

Vapor phase chlorination of 1,1-dichloroethane

Monochloroacetylene occurring as an impurity in 1,1-dichloroethylene is removed by chemical reaction in the presence of an aqueous HCl/cuprous chloride catalyst composition.
