Abstract: Foamable compositions based on rigid organic polymers such as polyvinyl chloride contain as the plasticizer a blend of a) a liquid oligomeric ester of phthalic acid, at least one aliphatic dicarboxylic acid or a mixture thereof; and b) a total of at least 15 weight percent, based on total plasticizer, of at least one ester of benzoic acid and/or an alkyl-substituted benzoic acid.

Abstract: Shaped articles, including but not limited to films, moldings and extruded profiles exhibiting a unique combination of desirable properties including high surface energy, permanence of the plasticizer, and processability are prepared from polymer compositions comprising a rigid organic polymer and a unique class of polyesters as plasticizers. The shaped articles are printable using both organic solvent- and water-based inks.

Abstract: Superabsorbent polymer particles having a particle size of about 38 to about 300 ?m and a median particle size of about 180 ?m or less are disclosed. The superabsorbent polymer particles comprise at least one unneutralized acidic water-absorbing resin and at least one unneutralized basic water-absorbing resin. One embodiment is multicomponent superabsorbent particles wherein each particle contains at least one microdomain of the acidic resin in contact with, or in close proximity to, at least one microdomain of the basic resin. Mixed bed of multicomponent superabsorbent gel particles with particles of a second unneutralized water-ab-sorbing resin, and mixed bed of particles of an unneutral-ized acidic water-absorbing resin and an unneutralized basic water-absorbing resin, also are disclosed. Improved diaper cores containing the small particle size superabsorbent polymer particles also are disclosed.

Abstract: Multicomponent superabsorbent gel particles are disclosed. The multicomponent particles comprise at least one acidic water-absorbing resin and at least one basic water-absorbing resin. Each particle contains about 20% to about 40%, by weight, of the basic resin, based on the total weight of the acidic resin and basic resin present in the particle. Blends of multicomponent superabsorbent gel particles with particles of a second water-absorbing resin also are disclosed. Improved diaper cores containing particles of the multicomponent superabsorbent gel particles also are disclosed.
