Latest Patents
Mawatari holds a patent for an invention titled "Optically active polymer of chiral alkoxy-substituted phenylacetylene." This invention provides an optically active polymer obtained by polymerizing a chiral alkoxy-substituted phenylacetylene, such as p-(2-methylbutoxy)phenylacetylene. The polymerization occurs in an organic solvent, like triethylamine, using a rhodium complex compound as a catalyst. The resulting optically active polymer exhibits a significantly larger optical rotation than the monomeric compound and can display different colors, such as yellow and black, depending on the solvent used. Notably, the yellow polymer can turn black when exposed to specific organic solvent vapors, such as chloroform, and revert to yellow upon re-precipitation with methyl alcohol.
