Films which are clear, transparent, non-tacky, easily handleable, mechanically strong and stable at both low and high humidity conditions, and are rapidly soluble in cold and warm water are formed from blends of water soluble polyvinyl alcohol (partially hydrolyzed polyvinyl acetate) and polyacrylic acid, optionally with a plasticizer. The films are also heat sealable and biodegradable.

A foamed polystyrene board useful as a thermal insulating material is produced by melting a polystyrene having a melt index of from 0.5 to 5 under heat in an extruder, mixing the molten mass with a blowing agent composed of methyl chloride and dichlorodifluoromethane, and extruding the resulting foamable molten gel from the extruder. As a novel essential feature, a flowability improver having a me...

The method comprises the chemical-mechanical polishing of amorphous aluminum oxide surfaces to a high degree of perfection. The aluminum oxide surfaces are continuously wetted with a water-citric acid slurry containing a sort abrasive material. The continuously wiping of the aluminum oxide surface is accomplished with a firm surface (16) using pressure while maintaining a relative movement between...

The present invention relates to foams made of resol-type phenolic resins which do not discolor as quickly as prior-art phenolic foams. With the additive in accordance with the invention, even colored foams will not darken as readily. The foams in accordance with the invention contain as stabilizers salts of phosphinic acid or phosphonic acid, such as the primary alkali phosphites or the alkali ph...
