标题:Synthesis of 1,4-trans-polybutadiene using a lanthanide organic acid salt catalyst
发明人：LYNCH THOMAS J
权利人:BRIDGESTONE CORP
摘要:The invention provides a catalyst composition, comprising: (a) an organolithium compound; and, (b) an organic acid salt of lanthanide series element; wherein: (1) only components (a) and (b) are required to promote the synthesis of 1,4-trans-polybutadiene; (2) the ratio of component (a) to component (b) is selected to maximize formation of the trans structure of said 1,4-trans-polybutadiene; and, (3) components (a) and (b) are selected for enabling further diblock synthesis. The invention further contemplates a process for using the catalyst to synthesize 1,4-trans-polybutadiene and other polymers and copolymers having trans configuration in the conjugated diene monomer contributed units.

摘要:A simple approach to produce mixed Cu/Cu 2 O nanocrystals having a specific morphology by controlling the reaction temperature during Cu/Cu 2 O nanocrystals synthesis. Other variables are kept constant, such as the amount of reactants, while the reaction temperatures is maintained at a predetermined temperature of 70° C., 30° C. or 0° C., which are used to produce different and controlled morphologies for the Cu/Cu 2 O nanocrystals. The reaction mixture includes a copper ion contributor, a capping agent, a pH adjustor, and reducing agent. The reaction mixture is held at the predetermined temperature for three hours to produce the Cu/Cu 2 O nanocrystals. The synthesis method has advantages such as mass production, easy operation, and high reproducibility.

标 题:Synthesis of nanofibers of polyaniline and substituted derivatives
发明人：EPSTEIN ARTHUR J; CHIOU NAN-RONG
权利人:OHIO STATE UNIVERISTY
摘要:Novel, simple methods are presented directed to the synthesis of nanofibers of polyaniline and substituted derivatives. The production of these fibers is achieved via various methods by controlling the concentration of aniline monomer or substituted aniline derivatives or an oxidant in the reaction medium and maintaining said concentration at a level much lower than conventional polyaniline synthesis methods. Methods are disclosed relating to the use of a permeable membrane to control the release of a monomer and/or oxidant as well as a bulk polymerization method.

标题 :Process for the synthesis of multi-modal aqueous dispersions of polysiloxanes
发明人：CRAIG DANIEL HORACE; MORGAN WAYNE FRANCIS
权利人:GEN ELECTRIC
摘要:A process for the acid-catalyzed synthesis of polysiloxane emulsions is discussed. The process comprises preheating an aqueous reaction mixture, optionally comprising polysiloxane emulsion seeds, and optionally containing a surfactant, to a temperature of up to about 110 DEG C. and adding to the aqueous reaction mixture, water, an acid catalyst surfactant, and a polysiloxane precursor to form a polysiloxane emulsion comprising essentially multi-modal, optionally multi-layered particles having desired multi-modal particle sizes in a range of from about 100 nm to about 2 microns.
