  • Patent number: 6337365
    Abstract: An electronic/electric part used in a clean room in which the atmosphere is controlled to process a substrate in a semiconductor device industry, which contains a resin base material and additives added to the resin base material. The additives contain one or more materials selected from the group consisting of an anti-electrostatic agent made of a nonionic compound of a molecular weight of 350 or higher, an anti-oxidizing agent made of a phenolic compound of a molecular weight of 300 or higher, a lubricant, a plasticizer, a fire retardant, and a water repellent. The additives hardly releases gaseous organic substances from the resin base material under a condition where the part is used.

  • Publication number: 20010031804
    Abstract: The color stability of thermoplastic polymers comprising structural units derived from at least one 1,3-dihydroxybenzene and at least one organodicarboxylic acid is enhanced by combination with at least one photobleachable 4-aminocinnamic compound such as 4-dimethylaminocinnamaldehyde. The latter absorbs radiation in the range between about 360 nanometers and about 390 nanometers, balancing the radiation absorbed by hydroxybenzophenone moieties formed in the polymer.

  • Patent number: 6103798
    Abstract: Thermoplastic compositions are provided containing a saturated hydrocarbon amine oxide and stabilizer compositions are provided containing a saturated hydrocarbon amine oxide and a second stabilizer. The thermoplastic compositions exhibit good melt flow rate stability during processing and are useful for making molded and extruded articles. The stabilizer compositions are useful for addition to thermoplastics for the stabilization thereof. A method is also provided for stabilizing thermoplastic compositions and involves admixing a hydrocarbon amine oxide with a thermoplastic resin. The saturated hydrocarbon amine oxides are preferably trialkyl amine oxides. The thermoplastic resin is preferably a polyolefin resin.
