Latest Patents

Among his latest patents, Todd has developed methods for producing polyolefin products. One of his notable inventions involves a method of methylating a catalyst composition while substantially normalizing the enantiomeric distribution. This method includes slurrying an organometallic compound in dimethoxyethane (DME) and adding a solution of RMgBr in DME, where R can be a methyl group or a benzyl group. The RMgBr is utilized in quantities greater than about 2.3 equivalents relative to the organometallic compound. After the addition of RMgBr, the slurry is mixed for at least about four hours, resulting in the isolation of an alkylated organometallic. The methylated species achieved has a meso/rac ratio that ranges between about 0.9 and about 1.2.
