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.

标 题:Verdazyl agents for the production of free standing polymers
发明人：HICKS ROBIN GARY; GEORGES Michael
权利人:UNIV VICTORIA INNOVAT DEV
摘要:The present disclosure concerns embodiments of a method of synthesizing polymers using verdazyl agents selected for their property of being moderately unstable free radicals. In one embodiment of the invention a method of synthesizing free standing polymers from suitably selected polymerizable subunits, such as monomers, is provided. In another embodiment of the invention a combination for the synthesis of free standing polymers from suitably selected polymerizable subunits using moderately unstable verdazyls is provided. Using moderately unstable verdazyls permits lower reaction temperatures and faster reaction times, while yielding polymers with low polydispersity.

权利人:PROVIVI INC
摘要:Methods for preparation of olefins, including 8- and 11-unsaturated monoenes and polyenes, via transition metathesis-based synthetic routes are described. Metathesis reactions in the methods are catalyzed by transition metal catalysts including tungsten-, molybdenum-, and ruthenium-based catalysts. The olefins include insect pheromones useful in a number of agricultural applications.
