  • Patent number: 6527825
    Abstract: Disclosed is a process for preparing nanoscale metal-based powders from a metal salt and an amphiphilic copolymer containing ethylene oxide. The copolymer and metal salt are mixed to form a metal salt/copolymer paste which is then calcined at a temperature sufficient to remove water and organics and to form a metal oxide.

  • Patent number: 5892130
    Abstract: Disclosed is an oxyalkylene-modified polyoxybutylene alcohol having an improved viscosity index. Notably enhancement of the viscosity index is obtained when the polyoxybutylene alcohol contains an internal oxypropylene or oxyethylene block; and wherein the total amount of converted butylene oxide in the molecule is from 99 to 75 parts per 100 parts by weight of the total converted alkylene oxide.
