Patent ID: 11708430

Abstract:
This invention relates to a method comprising combining an alkylidyne catalyst compound and a terminal alkyne to form a ring polymer. The terminal alkyne has the formula RC2H, wherein R is H, an alkyl group having from 1 to 20 carbon atoms, a cycloalkyl group having from 3 to 20 carbon atoms, an aromatic group having from 6 to 20 carbon atoms, an alkenyl group having from 2 to 20 carbon atoms, or an alkynyl group having from 2 to 20 carbon atoms. The alkylidyne catalyst compound has the formula (R1)(R2)(R3) MCR4, where M is tungsten or molybdenum, R1, R2, and R3 is alkoxide, halide, oxide, nitride, or sulfide, and R4 is H, an aliphatic group having from 1 to 20 carbons, an aromatic group having from 1 to 20 carbons, or a heteroaryl group having from 1 to 20 carbons, wherein the heteroatom is nitrogen, oxygen, boron, or sulfur.
