Abstract: A method of preparing fibrous hydrophilic fluff having increased absorbency is disclosed. An absorbent polymer solution is coated on base fluffing material, and the coated fluffing material is dried, disintegrated and mechanically worked into a fibrous fluff matrix which contains absorbent polymer platelets distributed throughout said matrix.

Abstract: The corrosion resistance of dicyclopentadiene (DCPD) modified unsaturated polyester or DCPD modified unsaturated polyesteramide resins can be improved by replacing a part of the styrene used as a reactant diluent in the resin with materials, such as divinylbenzene.

Abstract: Oxalic acid, alone or in combination with phenothiazine or with phenothiazine and 4-chloro-2-nitrophenol, increases the storage life of vinyl ester resins or unsaturated polyesters without adversely suppressing the exotherm or affecting their curability.

Abstract: A cured resin system is used to encapsulate certain liquid low level radioactive wastes which are solvents for or are soluble in the uncured resin and which are more soluble in water than in the uncured resin. The process comprises the dilution of said waste with water to an extent that the amount of waste that will partition in the uncured resin system is less than the amount that will retard the cure rate of the system or that will adversely affect physical properties of the cured product, followed by the uniform dispersion of the aqueous solution in said curable resin system after which the resin system is cured to a solid with the aqueous waste solution dispersed therein.

Abstract: A novel polymer of a vinyl benzyl ether monomer and at least one other copolymerizable monomer, at least one of which other monomers has a carboxylic acid group, an anhydride group, a sulfate group, a sulfonate group or a hydroxyl group is disclosed. The vinyl benzyl ether monomer has the formula ##STR1## wherein R is hydrogen or methyl, m is about 10 to 100 and Y is ##STR2## where R.sub.1 is an alkyl, aralkyl or alkaryl hydrophobic group of 10 to about 22 carbon atoms, R.sub.2 is an alkyl group of 1 to about 22 carbon atoms and R.sub.3 is hydrogen or an alkyl group of 1 to about 22 carbon atoms, provided R.sub.2 and R.sub.3 in combination have at least 10 carbon atoms.
