  • Patent number: 7026373
    Abstract: A polyamphoteric superabsorbent copolymer made up of polymerizerable acid monomer and of polymerizable base monomer and optionally a supplemental monomer. In particular, the invention includes a radiation curable coating composition that comprises from about 20 weight % to about 80 weight % of polymerizerable acid monomer and from about 20 weight % to about 80 weight of polymerizable base monomer; and from 0 weight % to about 50 weight % of supplemental monomer. On exposure to radiation the coating composition forms a polyamphoteric superabsorbent copolymer. The radiation curable coating composition may be used with suitable substrates.

  • Patent number: 7022402
    Abstract: An asymmetric multi-layer insulative film of improved internal adhesive strength is made by combining a layer of polyimide and a high-temperature bonding layer, the high-temperature bonding layer being derived from a high temperature base polymer made of poly(tetrafluoroethylene-co-perfluoro[alkyl vinyl ether]) (PFA) and optionally blended with from 0–60 weight percent poly(tetrafluoroethylene-co-hexafluoropropylene) (FEP). The polyimide and high-temperature bonding layer laminate optionally also contains a layer of unsintered, partially sintered, or totally sintered polytetrafluoroethylene (PTFE) bonded directly to the high-temperature bonding layer. In addition, the polyimide high-temperature bonding layer laminate may be adhered to a poly(tetrafluoroethylene-co-hexafluoropropylene) (FEP) adhesive primer layer to more effectively bond the polyimide core layer to the high-temperature bonding layer.

  • Patent number: 6896963
    Abstract: A two-part sizing system for making colorless, densified fiber pellets of a reinforcing fiber material. The densified product may be advantageously produced by first applying a precursor size composition to reinforcing fiber strands, chopping the reinforcing fiber strands into chopped strand segments, applying a binder size, and densifying the chopped strand segments to form densified fiber pellets. The binder size is formulated using a copolymer of maleic anhydride which generates a product free from discoloration. In the process of making the pellets, the sized chopped strands are densified by tumbling in a rotating chamber for a period of time sufficient to increase their density but insufficient to degrade the fibers to a point where composite articles formed from such pellets have lower tensile or impact strengths than comparable composite articles formed from unpelletized strand segments.
