  • Patent number: 6252009
    Abstract: Acrylic polymers are typically difficult to cure unless they contain specific curing sites, such as carbon-carbon double bonds. This invention offers a technique to rapidly cure acrylic polymers containing nitrile groups that do not possess typical curing sites, such as carbon-carbon double bonds. By utilizing the process of this invention, heat resistant thermoplastic vulcanizates with high-resistance to solvents can easily be prepared. The present invention more specifically discloses a process for curing an acrylic polymer which comprises distributing an aromatic compound having at least two nitrile oxide groups bonded thereto throughout the acrylic polymer, wherein the acrylic polymer contains nitrile groups, and wherein a bulky group is in at least one ortho position to the nitrile oxide group and wherein the bulky group is a moiety which is larger than a hydrogen atom.

  • Patent number: 6150469
    Abstract: A hydrophilic polymer is denatured with a gaseous denaturant or a powdery denaturant substance made from a liquid denaturant substance. The liquid denaturant substance is made into powders by, for example, a method of mixing the liquid denaturant substance with a water-insoluble compound, a method of cooling the liquid denaturant substance to or below its melting point to turn the same into a solid state. Consequently, the hydrophilic polymer can be denatured uniformly. In case that the hydrophilic polymer is denatured with a gaseous denaturant, the hydrophilic polymer and denaturant react with each other efficiently in a safe manner regardless of the size or shape of the hydrophilic polymer. In case that the hydrophilic polymer is denatured with the powdery denaturant substance, not only the liquid denaturant substance which is substantially in the solid state can be mixed with the hydrophilic polymer, but also the denaturation timing can be readily controlled.

  • Patent number: 5891967
    Abstract: The present invention provides a method of modifying the surface of a polymeric substrate, e.g., to improve the wettability of the polymer film surface and/or alter the reactivity of the surface of the substrate by further oxidation, comprising exposing the substrate to a flame. The flame is supported by a fuel and oxidizer mixture that includes an effective amount, for modifying the polymeric substrate, of at least one oxygen-containing compound that functions as a fuel substitute. Oxygen comprises between about 10 and 50 atomic percent of the compound. Large increases in the ASTM wetting test over that reported with conventional flame-treating processes, have been observed in films treated according to this invention. In addition, significant increases in polymer film surface oxidation levels have been observed.

  • Patent number: 5849847
    Abstract: Polyalkenylaromatic-polyethylene copolymers are prepared using protected functional organolithium initiators. Polymerization of an alkenylsubstituted aromatic monomer followed by ethylene, results in a protected functional block polystyrene-co-polyethylenyllithium. Termination with a functionalizing agent followed by deprotection produces polymeric products with high functionalization at the initiating chain-end and at least partial functionalization at the terminal chain-end.
